In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached. • https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2 https://github.com/torvalds/linux/commit/4a625ceee8a0ab0273534cb6b432ce6b331db5ee • CWE-476: NULL Pointer Dereference •
