Subject: CVE request: kernel: tomoyo: oops in tomoyo_mount_acl()
Description of problem:
In tomoyo_mount_acl() since 2.6.36, kern_path() was called without
checking dev_name != NULL. As a result, an unprivileged user can
trigger oops by issuing mount(NULL, "/", "ext3", 0, NULL) request.
Upstream fix:
