Doc Text:
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.

Description OSIDB Bzimport 2024-07-12 13:43:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: mtk-vcodec: potential null pointer deference in SCP

The return value of devm_kzalloc() needs to be checked to avoid
NULL pointer deference. This is similar to CVE-2022-3113.
