Memory Management Issue in Linux Kernel Affects Device Mapper Product

CVE-2023-53765

What is CVE-2023-53765?

A memory management issue exists within the Linux Kernel's device mapper component. The vulnerability arises during the cleanup of background tracker work objects, where a failure to correctly release queued tasks can lead to a kernel bug. Specifically, this occurs in the method btracker_destroy, as the system attempts to destroy a slab cache that still has objects remaining. This design flaw can disrupt normal kernel operations, potentially leading to instability and unexpected behavior.
