CVE-2024-53056

Summary

CVE-2024-53056 is a vulnerability affecting the Linux kernel that has been addressed. In the context of the Mediatek drm subsystem, a NULL dereference issue was identified in the function mtk_crtc_destroy(). This occurs when mtk_crtc_create() fails to obtain a channel during initialization, resulting in a NULL pointer for mtk_crtc->cmdq_client.chan. Subsequently, during cleanup, cmdq_pkt_destroy() is called unnecessarily on this NULL pointer, resulting in a potential NULL dereference. This issue has been rectified to prevent such unwarranted calls to cmdq_pkt_destroy().
