device-mapper-multipath: multipathd: insecure handling of files in /dev/shm leading to symlink attack

A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, in conjunction with CVE-2022-41974. Local users that are able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which may lead to...

kernel: dm cache: Fix UAF in destroy()

In the Linux kernel, the following vulnerability has been resolved: dm cache: Fix UAF in destroy Dmcache also has the same UAF problem when dmresume and dmdestroy are concurrent. Therefore, cancelling timer again in destroy...

kernel: dm thin: Use last transaction's pmd->root when commit failed

A metadata handling flaw was found in the Linux kernel device-mapper thin provisioning driver. After a failed metadata commit, the in-memory root pointer could reference a mixed set of fresh and stale tree nodes. Subsequent lookups may loop or stall. A local user could use this flaw to cause the...

kernel: dm thin: Fix UAF in run_timer_softirq()

In the Linux kernel, the following vulnerability has been resolved: dm thin: Fix UAF in runtimersoftirq When dmresume and dmdestroy are concurrent, it will lead to UAF, as follows: BUG: KASAN: use-after-free in runtimers+0x173/0x710 Write of size 8 at addr ffff88816d9490f0 by task swapper/0/0 Cal...

kernel: dm integrity: Fix UAF in dm_integrity_dtr()

A use-after-free vulnerability was found in the Linux kernel's device mapper integrity subsystem. When dmresume and dmdestroy execute concurrently, a timer may fire and access freed memory because dmintegritydtr did not properly cancel the timer before freeing resources. The fix adds an additiona...

kernel: dm clone: Fix UAF in clone_dtr()

A use-after-free vulnerability was found in the device-mapper clone target. When dmresume and dmdestroy execute concurrently, a timer may fire after the clone target structure has been freed, leading to use-after-free...

kernel: dm cache: free background tracker's queued work in btracker_destroy

A memory leak was found in the device-mapper cache target in the Linux kernel. The btrackerdestroy function fails to free queued work items from the background tracker before destroying the slab cache. This triggers a BUG when kmemcacheshutdown finds objects still remaining...

ALSA-2023:2459 Moderate: device-mapper-multipath security and bug fix update

The device-mapper-multipath packages provide tools that use the device-mapper multipath kernel module to manage multipath devices. Security Fixes: device-mapper-multipath: multipathd: insecure handling of files in /dev/shm leading to symlink attack CVE-2022-41973 For more details about the securi...

PT-2025-41054

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contained a deadlock situation between the shrink slab and dm pool abort metadata processes. This occurred due to concurrent processes involving dropping caches and...

The vulnerability of the verity_ctr() function in the drivers/md/dm-verity-target.c module of the device-mapper subsystem in the Linux operating system allows a attacker to execute arbitrary code and connect vulnerable hardware devices.

The vulnerability of the verityctr function in the drivers/md/dm-verity-target.c file of the device-mapper subsystem in the Linux operating system is related to the lack of verification for the types of tables that are loaded. Exploiting this vulnerability allows an attacker with administrative...

Linux kernel denial of service vulnerability (CNVD-2023-51389)
