What to do
AI-suggested
A fix has been applied to the Linux kernel source code to add the missing null pointer check in the affected function. Users should update to the fixed kernel versions once available from their Linux distribution vendors. Since this is a code-level fix in the kernel, applying the official kernel patch or updating to a patched kernel version is the recommended mitigation.
Description
A null pointer dereference vulnerability was identified and fixed in the Linux kernel's AMD display driver code, specifically in the update_dchubp_dpp function for the dcn401 hardware. This flaw could cause a denial of service by crashing the kernel when a null pipe_ctx->plane_state pointer is dereferenced.
