In the Linux kernel, the following vulnerability has been resolved:

gfs2: Fix potential glock use-after-free on unmount

When a DLM lockspace is released and there ares still locks in that lockspace, DLM will unlock those locks automatically. Commit fb6791d100d1b started exploiting this behavior to speed up filesystem unmount: gfs2 would simply free glocks it didn't want to unlock and then release the lockspace. This didn't take the bast callbacks for asynchronous lock contention notifications into account, which remain active until until a lock is unlocked or its lockspace is released.

To prevent those callbacks from accessing deallocated objects, put the glocks that should not be unlocked on the sddeadglocks list, release the lockspace, and only then free those glocks.

As an additional measure, ignore unexpected ast and bast callbacks if the receiving glock is dead.

— MITRE

Linux Kernel is vulnerable to a denial of service, caused by Glock Use-After-Free on Unmount. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service.

    Patch fb6791d100d1b
  118. Configuration

    Configure/ensure GFS2 unmount logic adds glocks that should not be unlocked onto the sd_dead_glocks list, then release the DLM lockspace, and only afterwards free those glocks—so asynchronous AST/Bast lock contention callbacks do not access deallocated objects when the receiving glock is dead.

    GFS2 (sd_dead_glocks handling) sd_dead_glocks list = glocks that should not be unlocked
  119. Compensating control

    As an additional measure, ignore unexpected ast and bast callbacks when the receiving glock is dead to prevent denial of service via the callback path.

  120. Compensating control

    Ignore unexpected AST/Bast callbacks for GFS2 lock contention notifications that remain active until a lock is unlocked or its lockspace is released, ensuring they cannot access deallocated glock objects.
