What to do

AI-suggested

A fix has been applied in the Linux kernel source code to add a null check for pipe_ctx->plane_state in the dcn20_program_pipe function. Users should update to the latest kernel version containing this fix to mitigate the issue.

Description

A null pointer dereference vulnerability was identified and fixed in the Linux kernel's AMD display driver, specifically in the dcn20_program_pipe function. The issue occurred when the pipe_ctx->plane_state pointer was null, leading to potential kernel crashes. The fix adds a null check to prevent dereferencing a null pointer.
