Details

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