Overview

CVE-2026-72015 is a known-severity vulnerability. It was published on August 15, 2026.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
