In the Linux kernel, the following vulnerability has been resolved:
slub/kunit: fix a WARNING due to unwrapped _kmalloccache_noprof
'modprobe slubkunit' will have a warning as shown below. The root cause is that _kmalloccachenoprof was directly used, which resulted in no alloctag being allocated. This caused current->alloctag to be null, leading to a warning in alloctagadd_check.
Let's add an allochook layer to _kmalloccachenoprof specifically within lib/slub_kunit.c, which is the only user of this internal slub function outside kmalloc implementation itself.
