Gfs2-utils: gfs2-utils: heap out-of-bounds read via unchecked ea_num_ptrs in extended attribute processing

Published Sep 3, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
A heap out-of-bounds read vulnerability was found in gfs2-utils. The ea_num_ptrs field from on-disk extended attribute metadata is consumed without bounds validation, causing a heap buffer over-read that may disclose sensitive memory contents or cause a crash when processing crafted GFS2 filesystem images.

Remediation

Vendor Workaround

Do not process untrusted GFS2 filesystem images with gfs2-utils tools. Run gfs2-utils tools in a containerized or VM-isolated environment when processing untrusted images.
