The vulnerability has been fixed in Linux kernel version 6.9 and associated commits. Users and administrators should update to the fixed kernel versions to remediate this issue. No additional mitigation is required beyond applying the official fix.
Description
A memory leak vulnerability in the Linux kernel's XFS filesystem was fixed. The flaw involved the function xqcheck_mod_live_ino_dqtrx not freeing a newly allocated dqa object if insertion into a resizable hash table (rhashtable) failed, causing a resource leak.
