In the Linux kernel, the following vulnerability has been resolved:
vtioctl: fix arrayindexnospec in vtsetactivate
arrayindexnospec ensures that an out-of-bounds value is set to zero on the transient path. Decreasing the value by one afterwards causes a transient integer underflow. vsa.console should be decreased first and then sanitized with arrayindexnospec.
