CVE-2024-44973 [MEDIUM] CWE-20 kernel: mm, slub: do not call do_slab_free for kfence object
kernel: mm, slub: do not call do_slab_free for kfence object
In the Linux kernel, the following vulnerability has been resolved:
mm, slub: do not call do_slab_free for kfence object
In 782f8906f805 the freeing of kfence objects was moved from deep
inside do_slab_free to the wrapper functions outside. This is a nice
change, but unfortunately it missed one spot in __kmem_cache_free_bulk.
This results in a crash like this:
