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.
