Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix unlikely race in gdlm_put_lock
In gdlm_put_lock(), there is a small window of time in which the DFL_UNMOUNT flag has been set but the lockspace hasn't been released, yet. In that window, dlm may still call gdlm_ast() and gdlm_bast(). To prevent it from dereferencing freed glock objects, only free the glock if the lockspace has actually been released.
