Уязвимость реализации технологии Single Thread Indirect Branch Predictors (STIBP) ядра операционной системы Linux, позволяющая нарушителю получить несанкционированный доступ к защищаемой информации

A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality.
