Title:
ASAN catches bug in v4l kernel module.
Status in linux package in Ubuntu:
Confirmed
Bug description:
The package linux-modules-extra-5.19.0-29-generic has a kernel module
named vivid.ko for artificial v4l streams.
When I modprobe the vivid.ko module, an invalid operation is detected
by ASAN, and the created of /dev/video0 device file fails.
The offending call is v4l_querymenu
The offending operation is shift-out-of-bounds
I tried this in a virtual machine of lunar (23.04) where the modprobe
succeeded. But it fails on the real machine, running kinetic (22.10)
This is a kernel bug.
