Gather Data Sampling vulnerability (GDS) - CVE-2022-40982 - Red Hat Customer Portal

Gather Data Sampling (GDS) (also known as “Downfall”) is a transient execution side-channel vulnerability affecting certain Intel CPUs. It may allow an attacker to use a data sampling attack, similar to Microarchitectural Data Sampling (MDS), to retrieve stale data from previously used AVX2 or AVX-512 vector registers. In the worst case scenario, such an attack can be used to extract cryptographic keys.
