CVSS v3.1 |
| NivoCart through 2.4.0 contains a destructive configuration write vulnerability in the admin password reset controller that allows unauthenticated attackers to disable password recovery by supplying an invalid code parameter. Attackers can send a GET request with a missing or incorrect code to rewrite the config_password setting to 0, disabling self-service password recovery until an administrator manually re-enables it. |

net: sparx5: fix sleep in atomic context in MAC table access
sparx5_set_rx_mode() runs with netif_addr_lock_bh held and iterates
dev->mc via __dev_mc_sync(), which per address calls sparx5_mc_sync() /
sparx5_mc_unsync() -> sparx5_mact_learn() / sparx5_mact_forget(). These
take sparx5->lock, a mutex, and then poll the MAC access command
register with readx_poll_timeout(). A mutex may block, which is not
allowed from atomic context.
Convert the driver to the new .ndo_set_rx_mode_async callback introduced
in commit 3554b4345d85 ("net: introduce ndo_set_rx_mode_async and
netdev_rx_mode_work"). The async callback is invoked from process
context, so the mutex and sleeping completion poll can remain.
Observed with CONFIG_PROVE_LOCKING, CONFIG_DEBUG_SPINLOCK,
CONFIG_DEBUG_MUTEXES and CONFIG_DEBUG_ATOMIC_SLEEP enabled:

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: do not leak an hci_conn when a second LE connect is rejected
create_le_conn_complete() decides whether the failed connection is
still pending by comparing it against hci_lookup_le_connect(), which
returns the first LE connection in BT_CONNECT. That is the same
connection only while at most one is pending.
Two can be pending. Connections created on the passive scan path sit
in BT_CONNECT with HCI_CONN_SCANNING set and are invisible to
hci_lookup_le_connect() until hci_le_create_conn_sync() clears the
flag when their command is issued, so the -EBUSY guard in
hci_connect_le() does not prevent a second connection from being
queued while the first is still on the scan path. Whenever two
connections are in BT_CONNECT at once, the lookup may return one
connection while create_le_conn_complete() is reporting the failure
of the other; the early exit then drops the error and hci_conn_failed()
never runs on the connection that failed.
The controller also rejects a second HCI_OP_LE_CREATE_CONN issued
while another connection creation is still outstanding, per Core Spec
Vol 4, Part E. The spec calls for Command Disallowed there; the
bcm43438 observed here answers with an LMP/LL error code instead,
which bt_to_errno() maps to the -EPROTO (-71) in the log below.
The leaked connection stays in BT_CONNECT forever, and because
hci_connect_le() refuses to dial while hci_lookup_le_connect() finds
anything, every subsequent attempt to reach any peer fails with
-EBUSY and no command reaches the controller at all.
Seen on a bcm43438 with two BLE peers polled on the same interval
(state 5 is BT_CONNECT; both handles are UNSET ones, allocated from
the ida above HCI_CONN_HANDLE_MAX):
Bluetooth: hci1: Opcode 0x2013 failed: -71
# hcitool con
< LE 14:9C:EF:03:68:81 handle 3840 state 5 lm CENTRAL
< LE C4:D3:6A:8C:B5:38 handle 3841 state 5 lm CENTRAL
A btmon capture across the next ten minutes of connect attempts
contains no HCI_OP_LE_CREATE_CONN at all; outgoing LE connections
do not recover until the adapter is reset. With this change the same
scenario fails the rejected connection cleanly and further connects
to both peers go through.
Ask about the connection itself instead of about the device. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: devres: fix cleanup in devm_clk_get_optional_enabled_with_rate()
devm_clk_get_optional_enabled_with_rate() registers its cleanup action
before setting the clock rate. If setting the rate fails, it attempts to
disable and unprepare a clock that was never enabled. This issue was
spotted while reviewing "rust: clk: add devres-managed clks" [1].
Register the cleanup action only after successfully preparing and enabling
the clock.

| In the Linux kernel, the following vulnerability has been resolved:
mtd: ubi: Release device reference on busy detach
ubi_detach_mtd_dev() obtains a device reference through ubi_get_device()
before checking whether the UBI device is busy. The busy return path drops
ubi->ref_count but leaves the device reference held, so the device object
cannot be released after a later detach.
Drop the device reference before returning -EBUSY. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fix the SCO setup context lifetime
hci_setup_sync() queues a conn_handle_t with a NULL destroy callback, so
the context is only freed if hci_enhanced_setup_sync() actually runs. An
entry that is cancelled instead is leaked, as
_hci_cmd_sync_cancel_entry() does not release entry->data when there is
no destroy callback, and hci_cmd_sync_clear() cancels every pending entry
when the controller is unregistered.
The context also stores a bare hci_conn pointer, so the connection can be
freed while the work is queued. The dequeue in hci_conn_del() does not
cover it either, as it matches on entry->data == conn and entry->data is
the wrapper here. Same problem as commit 2f5d635ad590 ("Bluetooth:
hci_sync: hold conn in hci_connect_acl/le_sync() callbacks").
Hold the connection and release both from a destroy callback. The
submission failure path drops both, since hci_cmd_sync_submit() does not
call the destroy callback when it fails to queue. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF (de)init
A user VINTF is torn down by tegra241_cmdqv_deinit_vintf(), which runs from
the destroy callback and from the init-failure unwind in the alloc handler.
It clears the cmdqv->vintfs[] slot and lets the iommufd core free it, but
nothing serializes that against the error interrupt: tegra241_cmdqv_isr()
reads cmdqv->vintfs[idx] and dereferences the vintf. A concurrent error can
make the ISR read a slot mid-clear (a NULL deref) or use a vintf which is
about to be freed (a use-after-free).
deinit_vintf() also returns idx to the IDA before clearing the slot, so a
concurrent create that reuses idx can publish its new vintf into the slot,
only for this teardown to erase it again with the stale NULL store.
On the other end, tegra241_cmdqv_init_vintf() publishes a new vintf with a
plain store to the cmdqv->vintfs[] slot, and the ISR dereferences fields of
a published vintf such as vintf->base. A plain store gives no ordering on a
weakly-ordered CPU, and a stale VINTF_ERR_MAP bit on a reused idx can make
the ISR pick a vintf the moment it is published, before its fields are set
or tegra241_vintf_hw_init() runs.
The cmdqv->vintfs[0] slot stays NULL until tegra241_cmdqv_init_structures()
first creates VINTF0, so the slot 0 read needs the same NULL check.
Publish every slot with an smp_store_release(), and read each slot in the
ISR with an smp_load_acquire() under a NULL check, so the ISR always sees
a fully built vintf or NULL. Also make deinit_vintf() clear the slot, and
synchronize_irq() prior to returning idx to the IDA, so no vintf is freed
under a running handler and no reused idx is clobbered. |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 8.0.6, the FTP parser in src/app-layer-ftp.c treats a RETR or STOR command sent before PORT or PASV negotiation as a fatal application-layer error instead of a recoverable protocol event. The fatal state disables FTP application-layer parsing for the remainder of the TCP flow, so later commands can evade parser-dependent rules and logging; IPS mode instead drops the flow. This issue is fixed in version 8.0.6. |
| Improper state validation in Skia in Google Chrome prior to 153.0.8010.52 allowed a remote attacker to obtain cross-origin data via a crafted HTML page. (Chromium security severity: High) |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Clear buf on error in __bpf_get_task_stack
Both bpf_get_task_stack and bpf_get_task_stack_sleepable helpers that
use __bpf_get_task_stack have buf defined as ARG_PTR_TO_UNINIT_MEM
argument and we should initialize the buf on every return path.
Adding missing buf memset for __bpf_get_task_stack fail paths. This
provides deterministic buffer contents, which is useful when the buffer
is used directly as a map key. |
| In the Linux kernel, the following vulnerability has been resolved:
lib/test_hmm: fail dmirror_fault() when the mirrored mm is gone
dmirror_fault() is called from the dmirror_read() and dmirror_write()
retry loops after dmirror_do_read() or dmirror_do_write() finds a missing
device page table entry.
If the mirrored mm has already exited, mmget_not_zero() fails. The
current code returns 0 in that case, which tells the caller that faulting
succeeded even though no page was faulted and no device page table entry
was installed. The caller then retries the same address, hits -ENOENT
again, and can loop forever without making progress.
Return -EFAULT instead, so the ioctl fails when the mirrored mm is no
longer faultable. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Abort directly from the hardlockup handler
scx_hardlockup() defers the abort to an irq_work because exit claiming used
to take scx_sched_lock and couldn't run from NMI. The deferral is now
unnecessary - claiming is NMI-safe and asserting ->aborting is exactly what
breaks the live-locks that hard-lock CPUs. Call handle_lockup() directly and
drop the irq_work. This also makes the self-detected case recoverable: the
perf watchdog fires on the hard-locked CPU itself, where a queued irq_work
never runs with IRQs off.
Also fix the return value: %true used to be returned whenever sched_ext was
loaded, suppressing the kernel's hardlockup report even when the abort was
refused. Return %true only when this call initiated the abort. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: RISC-V: Check acpi_get_handle() status in riscv_acpi_add_prt_dep()
In riscv_acpi_add_prt_dep(), the acpi_get_handle() call can fail which
would leave link_handle uninitialized.
Fix it by checking the acpi_get_handle() return status and skip the entry
if it fails. |
| mport is the MidnightBSD Package Manager. Prior to 2.7.8, mport_verify_package() in libmport/verify.c could continue after MD5File() or SHA256_File() failed and compare an expected checksum with stale data in the hash buffer rather than a newly computed digest. An attacker able to influence an installed file or the conditions that make hashing fail could receive a misleading integrity result or hide a checksum failure. This issue is fixed in version 2.7.8. |
| OpenSlide is a C library for reading whole slide image files. Prior to 4.0.1, a behavior change in libtiff 4.7.1 causes the indirect TIFF tile path in src/openslide-decode-tiff.c and _openslide_tiff_read_tile() to request a full-height destination for a partial bottom tile row, allowing uninitialized heap memory to enter pixel data returned by openslide_read_region(). A crafted but valid slide can trigger the issue in TIFF-based formats other than Hamamatsu NDPI when a network service renders attacker-provided slides. Successful extraction depends on pixel transparency handling and recompression, OpenSlide with libtiff 4.7.0 or earlier is not affected, and official binary builds 4.0.0.10 and 4.0.0.11 are affected. This issue is fixed in OpenSlide 4.0.1 and official binary build 4.0.0.12. |
| In the Linux kernel, the following vulnerability has been resolved:
tls: fix handling of zero-length records on the rx_list
Each recvmsg() call must process either
- only contiguous DATA records (any number of them)
- one non-DATA record
If the next record has different type than what has already been
processed we break out of the main processing loop. If the record
has already been decrypted (which may be the case for TLS 1.3 where
we don't know type until decryption) we queue the pending record
to the rx_list. Next recvmsg() will pick it up from there.
Queuing the skb to rx_list after zero-copy decrypt is not possible,
since in that case we decrypted directly to the user space buffer,
and we don't have an skb to queue (darg.skb points to the ciphertext
skb for access to metadata like length).
Only data records are allowed zero-copy, and we break the processing
loop after each non-data record. So we should never zero-copy and
then find out that the record type has changed. The corner case
we missed is when the initial record comes from rx_list, and it's
zero length. |
| mport is the MidnightBSD Package Manager. Prior to 2.7.8, libmport/util.c did not make every truncated, corrupt, or failed zstd stream fatal in mport_decompress_zstd(), and libmport/fetch.c did not consistently propagate those failures to index-fetch callers. A malicious or faulty mirror could supply compressed package index data that caused ZSTD_decompressStream() or an output write to fail while leaving partial index output available for later use, resulting in package-index integrity loss or denial of service. This issue is fixed in version 2.7.8. |

Otherwise in f2fs_sanity_check_node_footer(), it will check the

| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Don't query firmware state while chip is down
qla2x00_fw_state_show() initializes rval to QLA_FUNCTION_FAILED and jumps
to the out: label when the chip is down or EEH is busy. The out: block
then re-issued qla2x00_get_firmware_state() because rval != QLA_SUCCESS,
defeating the chip-down/EEH-busy guards and issuing a mailbox command
(outside optrom_mutex) during ISP reset or PCI error recovery, which can
hang the adapter. It also turned a normal in-lock mailbox failure into a
second unsynchronized mailbox attempt.
Make the out: fallback only mark the firmware state as unknown. The
mailbox is now issued at most once, inside optrom_mutex, and only when
the chip is up and not EEH-busy. |
