kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path

A flaw was found in the Linux kernel's keyring handling code: the keyrejectandlink function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation...
