Security Vulnerabilities - CVEs Published In October 2025
In the Linux kernel, the following vulnerability has been resolved:
mm/uffd: fix warning without PTE_MARKER_UFFD_WP compiled in
When PTE_MARKER_UFFD_WP not configured, it's still possible to reach pte
marker code and trigger an warning. Add a few CONFIG_PTE_MARKER_UFFD_WP
ifdefs to make sure the code won't be reached when not compiled in.

In the Linux kernel, the following vulnerability has been resolved:
clk: samsung: Fix memory leak in _samsung_clk_register_pll()
If clk_register() fails, @pll->rate_table may have allocated memory by
kmemdup(), so it needs to be freed, otherwise will cause memory leak
issue, this patch fixes it.

In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Validate the box size for the snooped cursor
Invalid userspace dma surface copies could potentially overflow
the memcpy from the surface to the snooped image leading to crashes.
To fix it the dimensions of the copybox have to be validated
against the expected size of the snooped cursor.

In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Lag, fix failure to cancel delayed bond work
Commit 0d4e8ed139d8 ("net/mlx5: Lag, avoid lockdep warnings")
accidentally removed a call to cancel delayed bond work thus it may
cause queued delay to expire and fall on an already destroyed work
queue.
Fix by restoring the call cancel_delayed_work_sync() before
destroying the workqueue.
This prevents call trace such as this:

In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate buffer length while parsing index
indx_read is called when we have some NTFS directory operations that
need more information from the index buffers. This adds a sanity check
to make sure the returned index buffer length is legit, or we may have
some out-of-bound memory accesses.

drm/rockchip: lvds: fix PM usage counter unbalance in poweron
pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
We fix it by replacing it with the newest pm_runtime_resume_and_get

In the Linux kernel, the following vulnerability has been resolved:
efi: ssdt: Don't free memory if ACPI table was loaded successfully
Amadeusz reports KASAN use-after-free errors introduced by commit
3881ee0b1edc ("efi: avoid efivars layer when loading SSDTs from
variables"). The problem appears to be that the memory that holds the
new ACPI table is now freed unconditionally, instead of only when the
ACPI core reported a failure to load the table.
So let's fix this, by omitting the kfree() on success.

Fault injection context as follows:
kobject_add
blk_mq_register_hctx
blk_mq_sysfs_register
blk_register_queue
device_add_disk
null_add_dev.part.0 [null_blk]
As 'blk_mq_register_hctx' may already add some objects when failed halfway,
but there isn't do fallback, caller don't know which objects add failed.
To solve above issue just do fallback when add objects failed halfway in
'blk_mq_register_hctx'.
