Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
Heap out-of-bounds read in gfs2-utils enables memory disclosure and potential crashes when parsing crafted GFS2 filesystem images. The ea_num_ptrs field embedded in on-disk extended attribute metadata is consumed without validating it against the available buffer boundary, allowing an attacker who controls a filesystem image to trigger a heap over-read. …
