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.
