Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to an incorrect bitwise shift operation in the Linux kernel, specifically in the JFS file system. The problem occurs when the
l2nbperpage value is negative, which can cause an error when used as a shift exponent. This can potentially allow an attacker to access confidential data, disrupt its integrity, and cause a denial of service. The vulnerability was reported by Syzbot, and the error is identified as a shift-out-of-bounds in the fs/jfs/jfs dmap.c file.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
