Name of the Vulnerable Software and Affected Versions Android versions 7.0 through 9.0

Description The issue is related to the impeg2 fmt conv yuv420p to yuv420sp uv av8 function in the Media framework component of the Android operating system. It involves an out-of-bounds write due to a missing bounds check, which could lead to remote code execution. User interaction is required for exploitation.
