Описание
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: add bounds checking to ocfs2_xattr_find_entry()
Add a paranoia check to make sure it doesn't stray beyond valid memory
region containing ocfs2 xattr entries when scanning for a match. It will
prevent out-of-bound access in case of crafted images.
A flaw was found in the ocfs2 component of the Linux kernel. A local attacker with low privileges could exploit this vulnerability by providing a crafted image. This could lead to an out-of-bounds memory access, potentially resulting in information disclosure, data corruption, or system instability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
