Vulnerability details

The vulnerability allows a local user to perform a denial of service (DoS) attack.

A memory leak flaw and potential divide by 0 and Integer overflow was found in the Linux kernel V4L2 and vivid test code functionality. This issue occurs when a user triggers ioctls, such as VIDIOC_S_DV_TIMINGS ioctl. This could allow a local user to crash the system if vivid test code enabled.
