| Kimi Code (@moonshot-ai/kimi-code) before 0.27.0 implements FetchURL SSRF hardening as a static hostname and IP-literal denylist in assertSafeFetchTarget, without resolving DNS or re-validating hosts after HTTP redirects. An attacker who can influence a FetchURL call (for example via prompt injection) can supply a crafted public hostname that resolves to loopback or another internal address, or a public URL that redirects to such a target, and thereby reach internal network services that the denylist was intended to block. FetchURL is included in the default auto-approve tool set, so the call does not require interactive user confirmation in manual mode. |
| Vulnerability in the Oracle Project Contracts product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Project Contracts. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Project Contracts accessible data as well as unauthorized access to critical data or complete access to all Oracle Project Contracts accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N). |
| cJSON library is vulnerable to an integer overflow in the print_string_ptr() function in cJSON.c on 32-bit platforms. The escape_characters counter, a 32-bit size_t, can wrap around when processing strings containing approximately 858,993,460 or more control characters, causing the output buffer to be allocated based on an underestimated length. When cJSON_PrintBuffered() is used with a pre-allocated buffer, the subsequent write loop overflows the heap allocation. An attacker supplying a crafted JSON string to an application using cJSON on a 32-bit platform can cause a heap buffer overflow, potentially leading to remote code execution, information disclosure, or denial of service.
Because project creator contact attempts were unsuccessful, the vulnerability has only been confirmed in version 1.7.19 but may also affect other versions. |
| A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in seunshare of selinux policycoreutils allows a user calling seunshare that is running in the unconfined SELinux domain to delete arbitrary root-owned files,
This issue affects policycoreutils through 3.10. |

| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: avoid double free of pool->stack on AQ init failure
otx2_pool_aq_init() frees pool->stack when mailbox sync or retry
allocation fails, but leaves the pointer unchanged. Later,
otx2_sq_aura_pool_init() unwinds the partial setup through
otx2_aura_pool_free(), which frees pool->stack again. The CN20K-specific
cn20k_pool_aq_init() implementation has the same bug in
its corresponding error path.
Set pool->stack to NULL immediately after the local free so the shared
cleanup path does not free the same stack again while cleaning up
partially initialized pool state.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still present in
v7.1-rc3.
Runtime validation was not performed because reproducing this path
requires OcteonTX2/CN20K hardware. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Disable broadcast TLB flush when PCID is disabled
Booting with "nopcid" clears X86_FEATURE_PCID and keeps CR4.PCIDE from being
set to one. On AMD CPUs that support INVLPGB, broadcast TLB flushing remains
enabled.
There are two checks that decide whether the global ASID code runs,
mm_global_asid() and consider_global_asid(), that key off of the
X86_FEATURE_INVLPGB feature. Once an mm becomes active on more than three
CPUs, consider_global_asid() assigns it a global ASID, after which
flush_tlb_mm_range() takes the broadcast_tlb_flush() path using a non-zero
PCID. Issuing an INVLPGB with a non-zero PCID while CR4.PCIDE is not set
results in a #GP:
Oops: general protection fault, kernel NULL pointer dereference 0x1: 0000 [#1] SMP NOPTI

All processors that support broadcast TLB invalidation also have PCID support,
so it is only the "nopcid" scenario that is of concern. In this situation just
disable the broadcast TLB support using the CPUID dependency support by making
X86_FEATURE_INVLPGB dependent on X86_FEATURE_PCID.

| In the Linux kernel, the following vulnerability has been resolved:
fuse-uring: fix moving cancelled entry to ent_in_userspace list
fuse_uring_cancel() moves entries that are available (these have no reqs
attached) to the ent_in_userspace list. ent_list_request_expired()
checks the first entry on ent_in_userspace and dereferences
ent->fuse_req unconditionally, which will crash on a cancelled entry
that was moved to this list.
Fix this by freeing the entry and dropping queue_refs directly in
fuse_uring_cancel(). This is safe because cancel is the cancel handler
itself - after io_uring_cmd_done(), no more cancels will be dispatched
for this command, and teardown serializes with cancel via queue->lock.
Since cancel now decrements queue_refs, fuse_uring_abort() must no
longer gate fuse_uring_abort_end_requests() on queue_refs > 0, as
cancelled entries may have already dropped queue_refs while requests are
still queued. Remove the gate so abort always flushes requests and stops
queues. |
| In the Linux kernel, the following vulnerability has been resolved:
fuse: clear intr_entry in fuse_resend and fuse_remove_pending_req
When fuse_resend() moves a request from fpq->processing back to
fiq->pending, it sets FR_PENDING and clears FR_SENT but does not
remove the requests intr_entry from fiq->interrupts. If the
request had FR_INTERRUPTED set from a prior signal, intr_entry
remains dangling on fiq->interrupts. When the requesting task
then receives a fatal signal, fuse_remove_pending_req() sees
FR_PENDING=1, removes the request from fiq->pending and frees it
via the refcount path, also without cleaning intr_entry. The
stale intr_entry causes use-after-free when fuse_read_interrupt()
iterates fiq->interrupts:
- list_del_init(&req->intr_entry) -> UAF write on freed slab
- req->in.h.unique -> UAF read, data leaked to userspace
Remove intr_entry from fiq->interrupts in fuse_resend() for
interrupted requests before they are placed back on fiq->pending.
Add a WARN_ON if the intr_entry is not empty on request destruction. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: nv: Avoid dereferencing NULL VNCR pseudo-TLB
VNCR TLB invalidation occurs from MMU notifiers or TLBI instructions,
and either can race against a vcpu not being onlined yet (no pseudo-TLB
allocated). Similarly, the TLB might be invalid, and the invalidation
should be skipped in this case.
Both kvm_invalidate_vncr_ipa() and kvm_invalidate_vncr_va() are
expected to perform the same checks, except that the latter doesn't
check for the allocation and blindly dereferences the pointer.
Solve this by introducing a new iterator built on top of the usual
kvm_for_each_vcpu() that checks for both of the above conditions,
and convert the two users to it. |
| In the Linux kernel, the following vulnerability has been resolved:
mm: page_ext: add count limit to page_ext_iter_next to prevent invalid PFN access
The page_ext iteration API does not validate if the PFN still belongs to a
valid section while advancing the iterator. When dynamically adding
memory in the hotplug path, it can lead to a NULL pointer dereference
during page_ext_lookup at the boundary of the last valid section when
iterator count equals __pgcount.
The for_each_page_ext() macro calls page_ext_iter_next() as its loop
increment. for_each_page_ext() does a "__page_ext =
page_ext_iter_next(&__iter)" at the end. This causes page_ext_iter_next()
to increment iter->index past __pgcount and call page_ext_lookup(start_pfn
+ __pgcount). During memory hotplug (online), the PFN at start_pfn +
__pgcount may belong to a section that has not yet been initialized,
causing page_ext_lookup() to trigger a NULL pointer dereference.

| In the Linux kernel, the following vulnerability has been resolved:
module: decompress: check return value of module_extend_max_pages()
module_extend_max_pages() calls kvrealloc() internally and returns
-ENOMEM on allocation failure. The return value is never checked.
If the initial allocation fails, info->pages remains NULL and
info->max_pages remains 0. Subsequent calls to module_get_next_page()
will attempt to dynamically grow the array by calling
module_extend_max_pages(info, 0) since info->used_pages is 0. This
results in kvrealloc(NULL, 0) returning ZERO_SIZE_PTR, which is treated
as a success, leading to a dereference of ZERO_SIZE_PTR and a kernel
oops.
Fix: add the missing error check after module_extend_max_pages() and
return immediately on failure. This matches the pattern used by every
other kvrealloc() caller in the module loading path.

| In the Linux kernel, the following vulnerability has been resolved:
crypto: chacha20poly1305 - validate poly1305 template argument
chachapoly_create() still accepts the compatibility poly1305 parameter
in the template name, but it assumes the second template argument is
always present and immediately passes it to strcmp().
When the argument is missing, crypto_attr_alg_name() returns an error
pointer. Check for that before comparing the name so malformed template
instantiations fail with an error instead of dereferencing the error
pointer in strcmp().
This matches the surrounding Crypto API template pattern where
crypto_attr_alg_name() results are validated before string-specific use. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: composite: fix dead empty check in the USB_DT_OTG handler
The OTG branch of composite_setup() falls back to the first
configuration when none is selected:
if (cdev->config)
config = cdev->config;
else
config = list_first_entry(&cdev->configs,
struct usb_configuration, list);
if (!config)
goto done;
...
memcpy(req->buf, config->descriptors[0], value);
list_first_entry() never returns NULL. On an empty list it returns
container_of() of the list head. So the "if (!config)" check is dead.
When cdev->configs is empty, config points at the head inside struct
usb_composite_dev. config->descriptors[0] reads whatever sits at that
offset. The memcpy copies up to w_length bytes of it into the response
buffer.
cdev->configs can be empty in two cases. One is a teardown race on
gadget unbind with a control transfer in flight. The other is a driver
that sets is_otg before it adds a config. A reproducer that holds
cdev->configs empty triggers a KASAN fault in this branch.
Use list_first_entry_or_null() so the existing check does its job. |
| In the Linux kernel, the following vulnerability has been resolved:
x86,fs/resctrl: Prevent out-of-bounds access while offlining CPU when SNC enabled
The architecture updates the cpu_mask in a domain's header to track which
online CPUs are associated with the domain. When this mask becomes empty
the architecture initiates offline of the domain that includes calling
on resctrl fs to offline the domain. If it is a monitoring domain in
which LLC occupancy is tracked resctrl fs forces the limbo handler to
clear all busy RMID state associated with the domain.
The limbo handler always reads the current event value associated with a
busy RMID irrespective of it being checked as part of regular "is it still
busy" check or whether it will be forced released anyway. When reading an
RMID on a system with SNC enabled the "logical RMID" is converted to the
"physical RMID" and this conversion requires the NUMA node ID of the
resctrl monitoring domain that is in turn determined by querying the NUMA
node ID of any CPU belonging to the monitoring domain.
When the monitoring domain is going offline its cpu_mask is empty causing
the NUMA node ID query via cpu_to_node() to be done with "nr_cpu_ids" as
argument resulting in an out-of-bounds access.
Refactor the limbo handler to skip reading the RMID when the RMID will
just be forced to no longer be dirty in the domain anyway. Add a safety
check to the architecture's RMID reader to protect against this scenario. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: gus: check snd_ctl_new1() return value
snd_ctl_new1() can return NULL when memory allocation fails.
snd_gf1_pcm_volume_control() does not check the return value before
dereferencing kctl->id.index, which can lead to a NULL pointer
dereference.
Add a NULL check after snd_ctl_new1() and return -ENOMEM if it fails. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: virtio: Validate control metadata from the device
virtio-snd control handling trusts the device-provided control type and
value count returned by the device.
That metadata is then used directly to index g_v2a_type_map[] in
virtsnd_kctl_info(), and to size loops and memcpy() operations in
virtsnd_kctl_get() and virtsnd_kctl_put() against fixed-size
virtio_snd_ctl_value and snd_ctl_elem_value arrays.
A buggy or malicious device can therefore trigger out-of-bounds access by
advertising an invalid control type or an oversized value count.
Validate control type and count once in virtsnd_kctl_parse_cfg(), before
querying enumerated items or exposing the control to ALSA. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ti-ads1119: fix PM reference leak in buffer preenable
ads1119_triggered_buffer_preenable() resumes the device with
pm_runtime_resume_and_get() before starting a conversion.
If i2c_smbus_write_byte() fails, the function returns the error directly
and leaves the runtime PM usage counter elevated. The matching
postdisable callback is not called when preenable fails, so the reference
is leaked and the device may remain runtime-active indefinitely.
Store the I2C transfer result in ret and drop the runtime PM reference on
failure before returning the error. |
