A vulnerability has been identified in Linux Kernel, which could be exploited by malicious users to cause a denial of service. This issue is caused by a NULL pointer dereference error in the "compat_sys_mount()" [fs/compat.c] function when converting data, which could be exploited by local attackers to panic an affected system and create a denial of service condition by mounting a smbfs file system in compatibility mode ("mount -t smbfs").
