CVE-2024-41017

Local kernel compromise via unchecked attribute bounds

Published Jul 29, 2024 · Updated Aug 5, 2026

Out-of-bounds access in Linux JFS allows local users to crash or compromise the kernel through a locally mounted crafted image. fs/jfs/xattr.c walks JFS extended-attribute entries using each entry's recorded size without first ensuring the entry remains inside the ealist buffer. Low-privileged access and the ability to mount the image are required; getxattr, listxattr, or an ACL permission check on the user's file reaches the faulty traversal.
