On August 8th, 2023, Intel disclosed a vulnerability in its recent computer processor microarchitecture. This vulnerability, known as "Gather Data Sampling (GDS)" or "Downfall", may allow an attacker to obtain sensitive information from a system. This vulnerability is assigned CVE ID as CVE-2022-40982 and has been given a medium severity by Intel.
CVE-2022-40982 is a transient execution side-channel vulnerability that affects Intel® Core processors from the 6th Generation (Skylake) to the 11th Generation (Tiger Lake). It allows an attacker with local access to infer stale data from previously used vector registers on the same physical core. A detailed description can be found in the “Downfall: Exploiting Speculative Data Gathering” paper.
If an attacker is able to exploit this vulnerability, they could potentially exfiltrate information contained within different security contexts (i.e., other virtual machines or even the host device).
