Linux Kernel SMBFS CHRoot Security Restriction Bypass Vulnerability

The Linux Kernel is prone to a vulnerability that allows attackers to bypass a security restriction. This issue is due to a failure in the kernel to properly sanitize user-supplied data.

The problem affects chroot inside of an SMB-mounted filesystem ('smbfs'). A local attacker who is bounded by the chroot can exploit this issue to bypass the chroot restriction and gain unauthorized access to the filesystem.
