CVE-2023-23005: Null Pointer Dereference

Published Mar 1, 2023
·
Updated

DISPUTED In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the allocmemorytype 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 allocmemorytype error case to be reached.
