| Vector | AV:L/AC:L/Au:S/C:C/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the ocfs2 subsystem, specifically in the
ocfs2 find victim chain() function. A kernel BUG occurs when the cl next free rec field within the allocation chain list is zero, triggering a condition that causes the kernel to panic. This happens because the code attempts to access a non-existent next free slot in the chain list. The issue is addressed by adding a check in ocfs2 claim suballoc bits() to verify if cl next free rec is zero or greater than cl count, and if so, logging an error instead of panicking the kernel.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
