CVE-2023-31084: Medium severity Linux Linux kernel vulnerability

Published Apr 24, 2023
·
Updated

A flaw in the Linux Kernel found in drivers/media/dvb-core/dvbfrontend.c. 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, waiteventinterruptible would put the process to sleep, and down(&fepriv->sem) may block the process.

Linux Kernel is vulnerable to a denial of service, caused by a blocking operation when a task is in !TASKRUNNING. In dvbfrontendgetevent, waiteventinterruptible is called in drivers/media/dvb-core/dvbfrontend.c. By sending a specially crafted request, a local attacker could exploit this vulnerability to cause a denial of service condition.
