CVE-2023-53753

An out-of-bounds array access was found in the AMD display driver in the Linux kernel. The driver allocates GPIO registers using incorrect bounds, leading to access of non-allocated memory addresses. This could cause kernel memory corruption or crashes during display initialization.

Exploitation requires an AMD GPU with the affected display controller code path. The out-of-bounds access occurs during driver initialization rather than through user-controlled input, limiting attack surface.
