Description OSIDB Bzimport 2026-10-23 12:06:07 UTC 
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
