AMD chipset driver has a flaw, users to install security updates as soon as possible
AMD recommends that Windows users who use their Ryzen 1000 to 3000 series processors install a security update as soon as possible because there is a high-risk vulnerability in the processor chipset driver that can be used by criminals to dump system memory to steal sensitive data.
The contents of those physical pages varied from kernel objects and arbitrary pool addresses that can be used to circumvent exploitation mitigations such as KASLR, and even registry key mappings of \Registry\Machine\SAM containing NTLM hashes of user authentication credentials that can be used in subsequent attack stages. For example, these can be used to steal credentials of a user with administrative privilege and/or be used in pass-the-hash style attacks to gain further access inside a network.
Microsoft has introduced monthly security updates, and this update also includes updates to the PSP driver chipset, so AMD also urges users to install it as soon as possible.
