CVE-2022-20369

An out-of-bounds write flaw was found in the Linux kernel’s UVC camera and similar device driver code due to improper input validation in the v4l2-mem2mem.c source code in how a user calls ioctl VIDIOC_QUERYBUF with mmap. This issue occurs if the capture buffer mapped directly from the userspace uses values from DQBUF, which returns an error. This flaw allows a local user to crash or escalate their privileges on the system.
