CVE-2024-56630
CVSS v2.0
6.8
Medium
| Vector | AV:L/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.74
Description
The issue is related to the ocfs2 file system in the Linux kernel, where the
ocfs2 get init inode() function fails to free an inode, leading to busy inodes after unmount. This occurs when new inode() succeeds but dquot initialize() fails, and the error is not properly handled. The problem was identified by syzbot, which reported busy inodes after unmount.Recommendations
For versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue. As a temporary workaround, consider disabling the
ocfs2 file system until a patch is available. Restrict access to the vulnerable ocfs2 module to minimize the risk of exploitation.Exploit
