Description:
A security issue has been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The security issue is caused due to a NULL pointer dereference error in the "compat_sys_mount()" function in fs/compat.c, which can be exploited to crash a vulnerable system by mounting an smbfs file system in compatibility mode.
Solution:
Update to version 2.6.21.1 or later.
