A logic error in the kernel's do_fault_around routine in memory.c can cause a use-after-free. A local user with no extra privileges could use it to escalate to higher privileges.

Affects systems running a Linux kernel where the flawed code path is present; the sources do not name affected kernel versions. Anyone with a local shell or code execution as an unprivileged user on such a machine is the realistic attacker. Systems with no untrusted local users carry lower risk.
