CVE-2024-40973
Description
A flaw was found in the mtk-vcodec module in the Linux kernel. The mtk_vcodec_fw_scp_init function in the drivers/media/platform/mediatek/vcodec/common/mtk_vcodec_fw_scp.c file does not check the return value of the devm_kzalloc function, potentially resulting in a NULL pointer dereference.
Statement
The mtk-vcodec module is not built in the kernel shipped in Red Hat Enterprise Linux, so it is not affected by this vulnerability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
