An issue was discovered in the Linux kernel through 5.16-rc6. mtk_vcodec_fw_vpu_init in drivers/media/platform/mtk-vcodec/mtk_vcodec_fw_vpu.c lacks check of the return value of devm_kzalloc() and will cause the null pointer dereference.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
