Red Hat: CVE-2024-56566: kernel: mm/slub: Avoid list corruption when removing a slab from the full list (Multiple Advisories)

A use-after-free list corruption vulnerability was found in the Linux kernel. If an allocated object fails in alloc_consistency_checks, all objects of the slab will be marked as used and the slab will be removed from the partial list. When an object belonging to the slab gets freed later, the remove_full() function is called. Since the slab is neither on the partial list nor on the full list, it eventually leads to a list corruption.
