Technical details
A heap out-of-bounds read (CWE-125) exists in gfs2-utils due to missing bounds validation on the ea_num_ptrs field from on-disk GFS2 extended attribute metadata. An attacker can craft a malicious GFS2 filesystem image that, when processed by gfs2-utils tools, triggers a heap buffer over-read. The vulnerability requires local access and user interaction (an administrator must explicitly run the tool on the crafted image). Exploitation can disclose sensitive memory contents through tool output or cause a denial-of-service crash if the over-read crosses a page boundary. The kernel GFS2 driver is not affected.
