Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.29

Description The issue allows local users to cause a denial of service, resulting in a system crash, by utilizing the mknod system call with a pathname on an NFSv4 filesystem. This is due to a problem in the encode share access function in fs/nfs/nfs4xdr.c.

Recommendations For versions prior to 2.6.29, update to version 2.6.29 or later to resolve the issue. As a temporary workaround, consider restricting access to the mknod system call on NFSv4 filesystems to minimize the risk of exploitation.
