Closed rrobgill closed 1 year ago

The ability to mitigate against this vulnerability was added to the kernel in Jan 2022 (https://lore.kernel.org/lkml/Yd8o%2FhxM%2FOH3mdQR@zn.tnic/) Detection is via kernel .config, as this mitigation is not reported in /sys

SLS affects AMD CPUs from Athlon XP through to Ryzen 5000 and EPYC server processors (https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1026) ( Related Issue #413 )
