CVE-2022-50079 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check correct bounds for stream encoder instances for DCN303 [Why & How] eng_id for DCN303 cannot be more than 1, since we have only two instances of stream encoders. Check the correct boundary condition for engine ID for DCN303 prevent the potential out of bounds access.
A vulnerability in the Linux kernel's AMD display driver for DCN303 stream encoders has been addressed. The issue was related to improper boundary checks for stream encoder instances, which could lead to out-of-bounds access. The engine ID for DCN303 should not exceed 1, as there are only two stream encoder instances available.
