CVE-2024-53201

Summary

CVE-2024-53201 is a newly identified vulnerability in the Linux kernel. Specifically, in the drm/amd/display subsystem, a null pointer dereference issue was discovered in the function dcn20_program_pipe(). Previously, a patch attempted to address this issue, but it did not fully resolve the problem. In certain conditions, the variable pipe_ctx could be null, and the function would attempt to access plane_state through it, resulting in a null pointer dereference. This vulnerability could potentially lead to system instability. To mitigate this issue, the latest patch adds necessary null checks to ensure the stability of the Linux kernel.
