| In the Linux kernel, the following vulnerability has been resolved:
dma-buf/dma-resv: check if the new fence is really later
Previously when we added a fence to a dma_resv object we always
assumed the the newer than all the existing fences.
With Jason's work to add an UAPI to explicit export/import that's not
necessary the case any more. So without this check we would allow
userspace to force the kernel into an use after free error.
Since the change is very small and defensive it's probably a good
idea to backport this to stable kernels as well just in case others
are using the dma_resv object in the same way. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: virtuser: fix potential out-of-bound write
If the caller wrote more characters, count is truncated to the max
available space in "simple_write_to_buffer". Check that the input
size does not exceed the buffer size. Write a zero termination
afterwards. |
| In the Linux kernel, the following vulnerability has been resolved:
alloc_tag: allocate percpu counters for module tags dynamically
When a module gets unloaded it checks whether any of its tags are still in
use and if so, we keep the memory containing module's allocation tags
alive until all tags are unused. However percpu counters referenced by
the tags are freed by free_module(). This will lead to UAF if the memory
allocated by a module is accessed after module was unloaded.
To fix this we allocate percpu counters for module allocation tags
dynamically and we keep it alive for tags which are still in use after
module unloading. This also removes the requirement of a larger
PERCPU_MODULE_RESERVE when memory allocation profiling is enabled because
percpu memory for counters does not need to be reserved anymore. |
| Crypto++ (aka cryptopp) through 5.6.4 does not document the requirement for a compile-time NDEBUG definition disabling the many assert calls that are unintended in production use, which might allow context-dependent attackers to obtain sensitive information by leveraging access to process memory after an assertion failure, as demonstrated by reading a core dump. |
| A cross-site scripting (XSS) vulnerability has been reported to affect QuLog Center. If a remote attacker gains an administrator account, they can then exploit the vulnerability to bypass security mechanisms or read application data.
We have already fixed the vulnerability in the following version:
QuLog Center 1.8.2.923 ( 2025/08/27 ) and later |
| An SQL injection vulnerability has been reported to affect QuMagie. A remote attacker can exploit the vulnerability to execute unauthorized code or commands.
We have already fixed the vulnerability in the following versions:
QuMagie 2.7.0 and later |
| A relative path traversal vulnerability has been reported to affect QuMagie. If a remote attacker, they can then exploit the vulnerability to read the contents of unexpected files or system data.
We have already fixed the vulnerability in the following version:
QuMagie 2.7.3 and later |
| A path traversal vulnerability has been reported to affect Qsync Central. If a remote attacker gains a user account, they can then exploit the vulnerability to read the contents of unexpected files or system data.
We have already fixed the vulnerability in the following version:
Qsync Central 5.0.0.3 ( 2025/08/28 ) and later |

| In the Linux kernel, the following vulnerability has been resolved:
binder: fix alloc->vma_vm_mm null-ptr dereference
Syzbot reported a couple issues introduced by commit 44e602b4e52f
("binder_alloc: add missing mmap_lock calls when using the VMA"), in
which we attempt to acquire the mmap_lock when alloc->vma_vm_mm has not
been initialized yet.
This can happen if a binder_proc receives a transaction without having
previously called mmap() to setup the binder_proc->alloc space in [1].
Also, a similar issue occurs via binder_alloc_print_pages() when we try
to dump the debugfs binder stats file in [2].
Sample of syzbot's crash report:

Fix these issues by setting up alloc->vma_vm_mm pointer during open()
and caching directly from current->mm. This guarantees we have a valid
reference to take the mmap_lock during scenarios described above.

| A cross site scripting vulnerability exists when Microsoft Dynamics 365 (on-premises) does not properly sanitize a specially crafted web request to an affected Dynamics server, aka 'Microsoft Dynamics 365 (On-Premise) Cross Site Scripting Vulnerability'. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort()
A race can occur between the MCQ completion path and the abort handler:
once a request completes, __blk_mq_free_request() sets rq->mq_hctx to
NULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call in
ufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer is
dereferenced, the kernel will crash.
Add a NULL check for the returned hwq pointer. If hwq is NULL, log an
error and return FAILED, preventing a potential NULL-pointer
dereference. As suggested by Bart, the ufshcd_cmd_inflight() check is
removed.
This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix
ufshcd_abort_one racing issue").
This is found by our static analysis tool KNighter. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: bcm: rpi: Prevent out-of-bounds access
The while loop in raspberrypi_discover_clocks() relies on the assumption
that the id of the last clock element is zero. Because this data comes
from the Videocore firmware and it doesn't guarantuee such a behavior
this could lead to out-of-bounds access. So fix this by providing
a sentinel element. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (gpio-fan) Fix array out of bounds access
The driver does not check if the cooling state passed to
gpio_fan_set_cur_state() exceeds the maximum cooling state as
stored in fan_data->num_speeds. Since the cooling state is later
used as an array index in set_fan_speed(), an array out of bounds
access can occur.
This can be exploited by setting the state of the thermal cooling device
to arbitrary values, causing for example a kernel oops when unavailable
memory is accessed this way.
