**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the `vt ioctl` function, specifically the `vt setactivate` call, where the `array index nospec` mechanism fails to properly sanitize an out-of-bounds value, leading to a transient integer underflow. The `vsa.console` value should be decreased first and then sanitized with `array index nospec` to prevent this issue. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
