Описание

In the Linux kernel, the following vulnerability has been resolved:

KVM: x86: use array_index_nospec with indices that come from guest

min and dest_id are guest-controlled indices. Using array_index_nospec() after the bounds checks clamps these values to mitigate speculative execution side-channels.
