A race condition was found in the Linux kernel’s mm/mremap memory address 
space accounting implementation, leading to a use-after-free vulnerability. 
This flaw allows a local user to cause a system crash or potentially 
escalate their privileges on the system. On RHEL it only affects RHEL 8 
and derivatives. It is only exploitable by a local user.
