CVE-2024-42121

CVE-2024-42121 is a Linux kernel vulnerability affecting the DRM/AMD display path. The issue arises from how msg_id is used as an array index and can be negative (not equal to MOD_HDCP_MESSAGE_ID_INVALID, -1). The root cause is missing validation of msg_id before read/write operations, leading to...
