| An Out-of-bounds Write vulnerability in the WatchGuard Fireware OS iked process may allow a remote unauthenticated attacker to execute arbitrary code. This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.
If the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured. |
| An HTTP Request Smuggling [CWE-444] vulnerability in the Authentication portal of WatchGuard Fireware OS allows a remote attacker to evade request parameter sanitation and perform a reflected self-Cross-Site Scripting (XSS) attack.
WatchGuard does not believe there is a practical exploit chain with a meaningful security impact for this vulnerability. |
| Metacat is data repository software that helps researchers preserve, share, and discover data. Versions 2.x through 2.19.1 and all 1.x versions contain an unauthenticated path traversal in the `archiveEntryName` parameter of the `action=read` endpoint that is part of the original 1.x Metacat API. `ArchiveHandler.readArchiveEntry()` concatenates the user-supplied parameter into a filesystem path without validation, and the surrounding `hasReadPermission()` check is commented out. An unauthenticated remote attacker can read any file accessible to the Tomcat process by sending a single GET request. Proof-of-concept exploits have been demonstrated and verified against this vulnerability, and it should be considered easily exploitable for any Metacat deployment < 3.0.0 by any user with access to the 1.x API. Through this vulnerability, production 2.x deployments are exposed to credential theft, client certificate and private key exfiltration enabling member node impersonation within the federation, embargoed research data disclosure, and broad system reconnaissance. Given Metacat's deployment footprint across the DataONE network of repositories and federally funded research programs, the population of exposed 2.x instances is non-trivial. The vulnerability was eliminated in Metacat version 3.0.0 and after by eliminating the entire Metacat 1.x API that exposed this vulnerability. The vulnerability was remediated in April 2024 with the release of Metacat 3.0.0, which removed the legacy Metacat API including ArchiveHandler.java. The commit message and issue reference architectural cleanup, not a security fix, and no advisory or CVE was issued. The 2.x branch was not and will not be backported, as is standard practice in Metacat, which only supports the most current release. 2.19.1 remains vulnerable with identical code and is beyond its supported lifetime. As a workaround, disable or restrict 1.x API servlets. Because the vulnerable 1.x API is no longer used or necessary in most Metacat deployments, restricting access to the old API endpoints can reduce or eliminate exposure for 2.19.x deployments. After removing those features, restart Tomcat or whichever software is hosting the servlets. |
| Versions of the package uplot before 1.6.31 are vulnerable to Prototype Pollution via the uplot.assign function due to missing check if the attribute resolves to the object prototype. |
| A stack-based buffer overflow vulnerability [CWE-121] in WatchGuard Fireware OS's certificate request command could allow an authenticated privileged user to execute arbitrary code via specially crafted CLI commands. |
| In the Linux kernel, the following vulnerability has been resolved:
media: stm32-dcmipp: Return queued buffers on start_streaming() failure
The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming(). If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.
dcmipp_bytecap_start_streaming() returned -EINVAL when the source
subdevice could not be resolved from the media graph, before
pm_runtime_resume_and_get() and media_pipeline_start() had been called.
The remaining error paths already converge on the err_buffer_done
label, which calls dcmipp_bytecap_all_buffers_done(...,
VB2_BUF_STATE_QUEUED). Jump to that label directly: the intermediate
err_pm_put / err_media_pipeline_stop labels are skipped, which is
correct because nothing they would undo has happened yet.
This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure"). |
| In the Linux kernel, the following vulnerability has been resolved:
media: rtl2832_sdr: Return queued buffers on start_streaming() failure
The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming(). If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.
rtl2832_sdr_start_streaming() had multiple error paths that hit this
trap: two direct early returns (-ENODEV, -ERESTARTSYS), plus six
`goto err` paths covering subdev s_power, tuner setup, ADC setup,
stream-buffer allocation, urb allocation, and urb submission failures.
None of them returned the queued buffers.
The original function had no distinct success exit and fell straight
through into the err label, which previously only did mutex_unlock and
"return ret". Adding queued-buffer cleanup at err must therefore be
paired with an explicit success return; otherwise every successful
start would also drain the buffer queue and kill streaming. Add that
success return, then add rtl2832_sdr_cleanup_queued_bufs() at the err
label and before each early return.
The cleanup helper takes a vb2_buffer_state argument so that the
start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as
expected by userspace on start_streaming failure) while stop_streaming
keeps its existing VB2_BUF_STATE_ERROR semantics.
This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").
The err label still does not roll back power_ctrl(), frontend_ctrl(),
the POWER_ON flag, or stream/URB allocations that may have happened
before the failing step. Those are pre-existing leaks of a different
class and are not addressed here. |
| In the Linux kernel, the following vulnerability has been resolved:
media: rtl2832: fix use-after-free in rtl2832_remove()
cancel_delayed_work_sync() is called before i2c_mux_del_adapters()
in rtl2832_remove(). While the cancel waits for any running instance
of i2c_gate_work to finish, it does not prevent the timer from being
rescheduled by a concurrent thread.
During probe, the r820t_attach() call attempts I2C transfers through
the mux adapter. These transfers go through i2c_mux_master_xfer(),
which calls rtl2832_deselect() after the transfer completes,
rescheduling i2c_gate_work via schedule_delayed_work(). If this
transfer is still in flight when rtl2832_remove() runs,
rtl2832_deselect() can reschedule i2c_gate_work after it has been
cancelled, causing a use-after-free when kfree(dev) is called.
Fix this by calling i2c_mux_del_adapters() before
cancel_delayed_work_sync(). Once the mux adapter is unregistered, no
new I2C transfers can go through it, so rtl2832_deselect() can no
longer reschedule i2c_gate_work. The subsequent
cancel_delayed_work_sync() is then guaranteed to be final. |
| In the Linux kernel, the following vulnerability has been resolved:
media: pwc: Drain fill_buf on start_streaming() failure
pwc_isoc_init() submits its isochronous URBs with
usb_submit_urb(.., GFP_KERNEL) in a loop. After the first URB is
submitted, its completion handler pwc_isoc_handler() can run on another
CPU before the loop finishes:
start_streaming()
pwc_isoc_init()
usb_submit_urb(urbs[0], GFP_KERNEL)
pwc_isoc_handler(urbs[0])
pdev->fill_buf =
pwc_get_next_fill_buf(pdev)
usb_submit_urb(urbs[i>0], ..) -> fails
pwc_isoc_cleanup(pdev) /* kills URBs */
return ret;
pwc_cleanup_queued_bufs(pdev, VB2_BUF_STATE_QUEUED)
pwc_get_next_fill_buf() detaches a buffer from pdev->queued_bufs and
stores it in pdev->fill_buf. The error path in start_streaming() only
drains pdev->queued_bufs, so the buffer parked in pdev->fill_buf is
leaked. vb2_start_streaming() then triggers
WARN_ON(owned_by_drv_count).
stop_streaming() already handles this since commit 80b0963e1698
("[media] pwc: fix WARN_ON"), which added the fill_buf drain in the
teardown path but not in the start_streaming() error path. Mirror that
handling on failure so start_streaming() returns with no buffer owned
by the driver.

| In the Linux kernel, the following vulnerability has been resolved:
media: nuvoton: npcm-video: fix memory leaks in probe and remove
npcm_video_probe() allocates the npcm_video structure with kzalloc_obj()
but never frees it on any probe error path or in npcm_video_remove(),
leaking the allocation on every failed probe and every normal unbind.
Additionally, when npcm_video_setup_video() fails, the reserved memory
association established by of_reserved_mem_device_init() in
npcm_video_init() is not released, leaking the rmem_assigned_device
entry on the global list.
Fix both by adding kfree(video) to all probe error paths and to
npcm_video_remove(), and adding the missing
of_reserved_mem_device_release() call when npcm_video_setup_video()
fails. |
| In the Linux kernel, the following vulnerability has been resolved:
media: meson: vdec: Fix memory leak in error path of vdec_open
The vdec_open() function previously jumped directly to
err_m2m_release when vdec_init_ctrls() failed, skipping
release of the m2m context. This caused a resource leak.
Fix it by introducing a proper err_m2m_ctx_release label
that calls v4l2_m2m_ctx_release(sess->m2m_ctx) before
releasing the m2m device.
This was identified via kmemleak:

| In the Linux kernel, the following vulnerability has been resolved:
net: hsr: fix memory leak on slave unregistration by removing synced VLANs
When an HSR master device is brought UP, it auto-adds VLAN 0 via
vlan_vid0_add(), which propagates VID 0 to its slave devices (slave A and B).
If a slave device is later unregistered while HSR is active (e.g., during
netns cleanup or interface destruction), hsr_del_port() is called to
detach the slave port from the HSR master. However, hsr_del_port() currently
does not delete the VLAN IDs that were synced to the slave device by HSR.
As a result, the slave device retains a refcount on VID 0 (and any other
synced VLANs). When the slave device is destroyed, its vlan_info /
vlan_vid_info structure remains allocated, leading to a memory leak.
Fix this by calling vlan_vids_del_by_dev(port->dev, master->dev) in
hsr_del_port() before unlinking slave A or slave B ports, matching the
propagation logic in hsr_ndo_vlan_rx_add_vid() / hsr_ndo_vlan_rx_kill_vid()
and the cleanup behavior in bonding and team drivers. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/vf: Add drm_dev guards when detaching CCS read/write buffers
CCS read/write buffers are freed during BO destruction. In some cases,
BOs may be destroyed after the device is unbound but while the DRM
structure remains valid, leading to NULL pointer dereferences when
accessing device resources.

wifi: mt76: mt7925: fix crash in reset link replay
During reset recovery, mt7925_vif_connect_iter() replays firmware state
for links tracked in mvif->valid_links. After MLO link changes or MCU
timeout recovery, the driver bitmap can temporarily contain a link whose
mac80211 bss_conf has already gone away.
This can pass a NULL bss_conf to mt76_connac_mcu_uni_add_dev(), matching
the crash where x1, the second argument, is NULL:
pc : mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]

mt7925_mac_reset_work+0x264/0x2f8 [mt7925_common]
Skip missing bss_conf entries before replaying the link. Non-MLO AP/STA
reset replay is unchanged because the helper still returns &vif->bss_conf
for the legacy link. |

wifi: mt76: mt7996: check pointer returned by mt76_connac_get_he_phy_cap()
mt76_connac_get_he_phy_cap routine can theoretically return NULL so

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: connac: fix possible NULL-pointer deref in mt76_connac_mcu_uni_bss_he_tlv()
mt76_connac_get_he_phy_cap routine can theoretically return NULL so
check cap pointer before dereferencing it. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: guard HE capability lookups
mt7915_mcu_bss_he_tlv() and mt7915_mcu_sta_bfer_tlv() both run after
checking HE support, then dereference the HE PHY capability returned by
mt76_connac_get_he_phy_cap(). That helper can return NULL when no
capability entry matches the vif type.
Fetch the capability before appending the TLV and skip the HE-specific
setup when no matching capability is available. |

net: mctp i3c: clean up notifier and buses if driver register fails
mctp_i3c_mod_init() registers the I3C bus notifier and then walks the
existing buses with i3c_for_each_bus_locked(mctp_i3c_bus_add_new, NULL)
before registering the I3C device driver. If i3c_driver_register()
fails, the function returns the error directly, leaving the notifier
registered and every mctp_i3c_bus object created for the existing buses
allocated. The notifier is left pointing into the module that failed to
load and the bus list is leaked.
Mirror the module exit path on this failure: unregister the notifier and
tear down the buses that were added before returning the error.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code. |
| In the Linux kernel, the following vulnerability has been resolved:
pds_core: fix use-after-free on workqueue during remove
In pdsc_remove(), the workqueue is destroyed before pdsc_teardown()
is called. This ordering allows two paths to queue work on the
destroyed workqueue:
1. If pdsc_teardown() -> pdsc_devcmd_reset() times out, the error
path in pdsc_devcmd_locked() queues health_work.
2. A NotifyQ event can trigger the ISR and queue work before free_irq()
is called in pdsc_teardown().
Fix by moving destroy_workqueue() after pdsc_teardown() so the
workqueue outlives every queuer; destroy_workqueue() then flushes any
work still pending.
Draining the queued work also requires ordering the teardown so the
resources that work touches are freed last:
- In pdsc_qcq_free(), after freeing the interrupt, cancel_work_sync()
the queue's work and only then clear qcq->intx, so
pdsc_process_adminq()'s read of qcq->intx for interrupt-credit
return cannot race with the clear.
- Free adminqcq before notifyqcq: the shared adminq ISR is released
when adminqcq is freed, and the adminq work accesses notifyqcq, so
both must be stopped before notifyqcq is freed. |
| In the Linux kernel, the following vulnerability has been resolved:
pds_core: fix deadlock between reset thread and remove
pci_reset_function() acquires device_lock before performing the reset.
pdsc_remove() is called by the PCI core with device_lock already held.
If pdsc_pci_reset_thread() is running when pdsc_remove() is called,
destroy_workqueue() will block waiting for the work to complete, while
the work is blocked waiting for device_lock - deadlock.
Use pci_try_reset_function() which uses pci_dev_trylock() internally.
This acquires both the device lock and the PCI config access lock
without blocking - if either lock is contended, it returns -EAGAIN
immediately. This avoids the deadlock while also ensuring proper
config space access serialization during the reset.
The pci_dev_get/put calls are also removed as they were unnecessary -
the driver-owned workqueue is destroyed in pdsc_remove(), guaranteeing
the work completes before remove returns. The PCI core holds its
reference to pci_dev throughout the entire unbind sequence. |
