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 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...
