A fix is available — apply it.

Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which incorrectly attempt to free a pointer which was not previously kmalloc()d, while at the same time leaking allocated memory. The bug can be triggered by an unprivileged local user and can result in the corruption of slab metadata and could lead to resource exhaustion.
