A fix is available and has been applied in the Linux kernel commits 60b0524bfb7d691ab378cdc788209f11cd34da89 and 9da4f9964abcaeb6e19797d5e3b10faad338a786. Users should update to a Linux kernel version that includes these commits to remediate the vulnerability.
Description
A vulnerability in the Linux kernel's AMD display driver was addressed by adding a check to ensure the ext_caps pointer is valid before accessing it during backlight setup. This prevents invalid memory access for LVDS connectors, which do not have extended backlight capabilities.
