In the Linux kernel, the following vulnerability has been resolved: slub/kunit: fix a WARNING due to unwrapped _kmalloccachenoprof '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 alloctagaddcheck. Let's add an allochook layer to _kmalloccachenoprof specifically within lib/slubkunit.c, which is the only user of this internal slub function outside kmalloc implementation itself.
