An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process.

CVE-2023-31084 [MEDIUM] media: dvb-core: Fix kernel WARNING for blocking operation in wait_event*()
media: dvb-core: Fix kernel WARNING for blocking operation in wait_event*()
Using a semaphore in the wait_event*() condition is no good idea.
It hits a kernel WARN_ON() at prepare_to_wait_event() like:
do not call blocking ops when !TASK_RUNNING; state=1 set at
prepare_to_wait_event+0x6d/0x690
For avoiding the potential deadlock, rewrite to an open-coded loop
instead. Unlike the loop in wait_event*(), this uses wait_woken()
after the condition check, hence the task state stays consistent.
CVE-2023-31084 was assigned to this bug.
