kernel: Report vmalloc UAF in dvb-core/dmxdev

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 privilege...
