CVSS v3.1
5.5
Média
| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.2.10
Description
The issue allows local users to cause a denial of service via attempted access to a special file, such as a FIFO. This occurs because the cifs code attempts to open files on lookup under certain circumstances, and if the opened file is a special file, the open filehandle is leaked, leading to a dentry refcount mismatch and an OOPS on umount.
Recommendations
For Linux kernel versions prior to 3.2.10, update to version 3.2.10 or later to resolve the issue. As a temporary workaround, consider restricting access to special files, such as FIFOs, to minimize the risk of exploitation.
