NVD Description

Note: Versions mentioned in the description apply only to the upstream libertas-sd8787-firmware package and not the libertas-sd8787-firmware package as distributed by RHEL.

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.
