From $URL :

Linux kernel built with support to VFAT file system is vulnerable to a buffer
overflow flaw which happens when converting UTF8 character string to UTF16
via function: utf8s_to_utf16s.

An unprivileged user could use this flaw to crash the kernel causing DoS or potentially escalate 
privileges.

There are no longer any 2.x or <3.3 kernels available in the repository with
the exception of sys-kernel/xbox-sources which is unsupported by security.
