Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper error handling in the XFS filesystem's xchk_scrub_create_subord function when processing scrub operations. A local user can trigger a memory allocation failure scenario that is not properly checked, leading to undefined behavior and potential system crash.
Exploitation requires local access and the ability to initiate XFS scrub operations. No authentication beyond local user privileges is required. The impact is limited to denial of service via system crash or hang.
