Description OSIDB Bzimport 2025-03-27 17:01:54 UTC 
In the Linux kernel, the following vulnerability has been resolved:

NFSD: fix use-after-free in nfsd4_ssc_setup_dul()

If signal_pending() returns true, schedule_timeout() will not be executed,
causing the waiting task to remain in the wait queue.
Fixed by adding a call to finish_wait(), which ensures that the waiting
task will always be removed from the wait queue.
