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 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...
