| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/uapi: Reject coh_none PAT index for CPU cached memory in madvise
Add validation in xe_vm_madvise_ioctl() to reject PAT indices with
XE_COH_NONE coherency mode when applied to CPU cached memory.
Using coh_none with CPU cached buffers is a security issue. When the
kernel clears pages before reallocation, the clear operation stays in
CPU cache (dirty). GPU with coh_none can bypass CPU caches and read
stale sensitive data directly from DRAM, potentially leaking data from
previously freed pages of other processes.
This aligns with the existing validation in vm_bind path
(xe_vm_bind_ioctl_validate_bo).

| A YAML injection vulnerability exists in the Windows.Collectors.Remapping artifact of Rapid7 Velociraptor before version 0.76.6. The hostname field in client_info.json inside a collection ZIP is inserted into a YAML template via Go's text/template without escaping. An attacker providing a crafted collection ZIP can leverage literal double quotes and newlines in the hostname to break out of the YAML quoted string and inject a new mount remapping entry. When an analyst applies the generated remapping file with --remap, arbitrary VQL executes on their machine with NullACLManager (all permissions granted, unsandboxed). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/zone_device: do not touch device folio after calling ->folio_free()
The contents of a device folio can immediately change after calling
->folio_free(), as the folio may be reallocated by a driver with a
different order. Instead of touching the folio again to extract the
pgmap, use the local stack variable when calling percpu_ref_put_many(). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/alloc_tag: clear codetag for pages allocated before page_ext initialization
Due to initialization ordering, page_ext is allocated and initialized
relatively late during boot. Some pages have already been allocated and
freed before page_ext becomes available, leaving their codetag
uninitialized.
A clear example is in init_section_page_ext(): alloc_page_ext() calls
kmemleak_alloc(). If the slab cache has no free objects, it falls back to
the buddy allocator to allocate memory. However, at this point page_ext
is not yet fully initialized, so these newly allocated pages have no
codetag set. These pages may later be reclaimed by KASAN, which causes
the warning to trigger when they are freed because their codetag ref is
still empty.
Use a global array to track pages allocated before page_ext is fully
initialized. The array size is fixed at 8192 entries, and will emit a
warning if this limit is exceeded. When page_ext initialization
completes, set their codetag to empty to avoid warnings when they are
freed later.
This warning is only observed with CONFIG_MEM_ALLOC_PROFILING_DEBUG=Y and
mem_profiling_compressed disabled:

| In the Linux kernel, the following vulnerability has been resolved:
vmalloc: fix buffer overflow in vrealloc_node_align()
Commit 4c5d3365882d ("mm/vmalloc: allow to set node and align in
vrealloc") added the ability to force a new allocation if the current
pointer is on the wrong NUMA node, or if an alignment constraint is not
met, even if the user is shrinking the allocation.
On this path (need_realloc), the code allocates a new object of 'size'
bytes and then memcpy()s 'old_size' bytes into it. If the request is to
shrink the object (size < old_size), this results in an out-of-bounds
write on the new buffer.
Fix this by bounding the copy length by the new allocation size. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: frequency: admv1013: fix NULL pointer dereference on str
When device_property_read_string() fails, str is left uninitialized
but the code falls through to strcmp(str, ...), dereferencing a garbage
pointer. Replace manual read/strcmp with
device_property_match_property_string() and consolidate the SE mode
enums into a single sequential enum, mapping to hardware register
values via a switch consistent with other bitfields in the driver.
Several cleanup patches have been applied to this driver recently so
this will need a manual backport. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: microchip: mpfs-ccc: fix out of bounds access during output registration
UBSAN reported an out of bounds access during registration of the last
two outputs. This out of bounds access occurs because space is only
allocated in the hws array for two PLLs and the four output dividers
that each has, but the defined IDs contain two DLLS and their two
outputs each, which are not supported by the driver. The ID order is
PLLs -> DLLs -> PLL outputs -> DLL outputs. Decrement the PLL output IDs
by two while adding them to the array to avoid the problem. |

| SAP Business Objects Business Intelligence Platform does not sufficiently validate email sending parameters supplied by authenticated users, resulting in an email spoofing vulnerability.This vulnerability has a low impact on integrity and does not affect the confidentiality and availability of the application. |
| Due to improper RFC protocol validation in the SAP Kernel used by the Application Server ABAP of SAP NetWeaver and ABAP Platform, an unauthenticated attacker can send a crafted RFC request that exploits logical errors in memory management, leading to memory corruption. This could lead to a high impact on the confidentiality, integrity, and availability of the application. |
| Application server ABAP does not perform necessary authorization checks for an authenticated user allowing an attacker to execute a report generation command which could overwrite information belonging to another user, resulting in escalation of privileges. This has high impact on integrity with low impact on availability and no impact on confidentiality of the application. |
| A vulnerability was identified in Dolibarr ERP CRM up to 23.0.2. The impacted element is an unknown function of the file htdocs/core/filemanagerdol/connectors/php/config.inc.php of the component Legacy Filemanager. The manipulation leads to improper authorization. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. Upgrading to version 23.0.3 is sufficient to resolve this issue. The identifier of the patch is f1b2dd6481e22cacb561d29ffdcd3a50b618479d. Upgrading the affected component is advised. |
| Out of bounds read in ANGLE in Google Chrome on Windows prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium) |
| A vulnerability was determined in DTStack Taier up to 1.4.0. The affected element is the function preHandle of the file taier-data-develop/src/main/java/com/dtstack/taier/develop/interceptor/LoginInterceptor.java of the component Source Connection Test Endpoint. Executing a manipulation can lead to improper authentication. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. This patch is called f95389e7f74acec42bcee079a616aaa06f9551d2. A patch should be applied to remediate this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
pseries/papr-hvpipe: Fix race with interrupt handler
While executing ->ioctl handler or ->release handler, if an interrupt
fires on the same cpu, then we can enter into a deadlock.
This patch fixes both these handlers to take spin_lock_irq{save|restore}
versions of the lock to prevent this deadlock. |
| In the Linux kernel, the following vulnerability has been resolved:
hfsplus: fix held lock freed on hfsplus_fill_super()
hfsplus_fill_super() calls hfs_find_init() to initialize a search
structure, which acquires tree->tree_lock. If the subsequent call to
hfsplus_cat_build_key() fails, the function jumps to the out_put_root
error label without releasing the lock. The later cleanup path then
frees the tree data structure with the lock still held, triggering a
held lock freed warning.
Fix this by adding the missing hfs_find_exit(&fd) call before jumping
to the out_put_root error label. This ensures that tree->tree_lock is
properly released on the error path.
The bug was originally detected on v6.13-rc1 using an experimental
static analysis tool we are developing, and we have verified that the
issue persists in the latest mainline kernel. The tool is specifically
designed to detect memory management issues. It is currently under active
development and not yet publicly available.
We confirmed the bug by runtime testing under QEMU with x86_64 defconfig,
lockdep enabled, and CONFIG_HFSPLUS_FS=y. To trigger the error path, we
used GDB to dynamically shrink the max_unistr_len parameter to 1 before
hfsplus_asc2uni() is called. This forces hfsplus_asc2uni() to naturally
return -ENAMETOOLONG, which propagates to hfsplus_cat_build_key() and
exercises the faulty error path. The following warning was observed
during mount:

| In the Linux kernel, the following vulnerability has been resolved:
selinux: allow multiple opens of /sys/fs/selinux/policy
Currently there can only be a single open of /sys/fs/selinux/policy at
any time. This allows any process to block any other process from
reading the kernel policy. The original motivation seems to have been
a mix of preventing an inconsistent view of the policy size and
preventing userspace from allocating kernel memory without bound, but
this is arguably equally bad. Eliminate the policy_opened flag and
shrink the critical section that the policy mutex is held. While we
are making changes here, drop a couple of extraneous BUG_ONs. |
| In the Linux kernel, the following vulnerability has been resolved:
flow_dissector: do not dissect PPPoE PFC frames
RFC 2516 Section 7 states that Protocol Field Compression (PFC) is NOT
RECOMMENDED for PPPoE. In practice, pppd does not support negotiating
PFC for PPPoE sessions, and the flow dissector driver has assumed an
uncompressed frame until the blamed commit.
During the review process of that commit [1], support for PFC is
suggested. However, having a compressed (1-byte) protocol field means
the subsequent PPP payload is shifted by one byte, causing 4-byte
misalignment for the network header and an unaligned access exception
on some architectures.
The exception can be reproduced by sending a PPPoE PFC frame to an
ethernet interface of a MIPS board, with RPS enabled, even if no PPPoE
session is active on that interface:
