Description
CVE-2024-47754 is a medium-severity vulnerability in the Linux kernel's MediaTek video codec driver. It involves a smatch static checker warning in the H264 multi stateless decoder code, specifically in vdec_h264_req_multi_if.c, which can lead to a kernel crash when a framebuffer (fb) pointer is NULL.
