Description
mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is not held during a PUD move.
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code in how a race condition happens between rmap walk and mremap. This flaw allows a local user to crash or potentially escalate their privileges on the system.
