AI-suggested
A patch is available and should be applied to affected Linux kernel versions to address this vulnerability. Users should update to the fixed kernel versions as provided by their distribution vendors. No additional mitigation is required beyond applying the official fix.
Description
A vulnerability in the Linux kernel's ASoC meson AIU HDMI and internal codec mux put callbacks allowed the use of written enum values without validating if they were within the valid range. This could lead to improper handling of out-of-range enum values. The issue has been resolved by adding validation to reject invalid enum values before conversion.
