Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)

array index nospec() boundary, which is a mechanism used to prevent speculative execution from accessing memory outside the intended bounds of an array. This allows potential access beyond the syscall function pointer tables.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
