Published: September 19, 2026
Vulnerability details
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to an integer overflow in the SOF topology volume table handling when processing topology mixer control data. A local user can provide topology mixer control data with an oversized maximum value to cause a denial of service.
An inverted minimum and maximum volume range is also invalid.
