Description

In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. A use-after-free flaw was found in the Linux kernel’s dvb-core subsystem (DVB API used by Digital TV devices) in how a user physically removed a USB device (such as a DVB demultiplexer device) while running malicious code. This flaw allows a local user to crash or potentially escalate their privileges on the system.
