CVE-2023-53765

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.0-rc2 #19

Description The Linux kernel contains an issue within the dm cache component. Specifically, the background tracker's queued work is not properly freed in the btracker destroy function. This can lead to a kernel BUG when the kmem cache shutdown function is called, potentially causing system instability. The issue arises from incomplete cleanup of work objects associated with the background tracker. A test case using lvm2-testsuite, specifically the "cache-single-split.sh" script, was used to identify the problem.

Recommendations Update to a version newer than 6.0.0-rc2 #19.
