Summary

The Linux kernel from 6.8 contains a flaw in the chips-media wave5 media driver. Invalid data in dec_output_info can make the driver write to invalid memory because the driver does not check the data's range.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Add range checks for dec_output_info If the driver's dec_output_info contains invalid data the driver can write in invalid memory. Add a range check for that. This fixes this smatch error: drivers/media/platform/chips-media/wave5/wave5-vpuapi.c:588 wave5_vpu_dec_get_output_info() error: buffer overflow 'inst->frame_buf' 64 <= 127
