Summary

In the Linux kernel's resctrl module, there is a double-free of the RMID for a pseudo-locked group. During unmount, rmdir_all_sub() unconditionally frees all RMIDs, leading to the same RMID being added to the free list twice.

Risk Assessment

Double-free can corrupt kernel data structures, potentially causing system crashes or privilege escalation.

Recommendation

Apply a Linux kernel update that includes the fix preventing double-free of RMID for pseudo-locked groups.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: fs/resctrl: Fix double-add of pseudo-locked region's RMID to free list A pseudo-locked group's RMID is freed when it is created. On unmount rmdir_all_sub() unconditionally frees all RMID of all groups, resulting in a double-free of the pseudo-locked group's RMID. The consequence of this is that the original free results in the pseudo-locked group's RMID being added to the rmid_free_lru linked list and the second free then attempts to add the same RMID entry to the rmid_free_lru again. Do not double-free a pseudo-locked group's RMID.
