*** This bug is a security vulnerability ***

Public security bug reported:

A flaw was found in the way the Linux kernel's futex subsystem handled
reference counting when requeuing futexes during futex_wait(). A local,
unprivileged user could use this flaw to zero out the reference counter
of an inode or an mm struct that backs up the memory area of the futex,
which could lead to a use-after-free flaw, resulting in a system crash
or, potentially, privilege escalation
