You can install the driver manually, but it’s available now through Windows Update. The latest version of the AMD PSP driver is 5.17.0.0, which is part of AMD Chipset Driver 3.08.17.735.

Read on learn how to update your drivers to make sure you have the latest version. With these exploits, attackers can steal sensitive information like passwords and gain deeper permissions in a network.Īlthough scary, AMD has already patched the vulnerability with a new PSP chipset driver, which rolled out last week through Microsoft’s September Patch Tuesday. The exploit also allows attackers to get around mitigations like kernel address space layout randomization (KASLR), which protect against attacks that exploit a known address for the kernel. The attack focuses in the motherboard chipset, so it doesn’t apply if you have an AMD graphics card without an AMD processor (though another security flaw is posing a risk to AMD cards at the moment).Īccording to the report, Economou was able to leak “several gigabytes” of data. The report says that all desktop and mobile Ryzen processors are affected, and AMD has updated its security disclosure since. Originally, AMD listed the vulnerability as only affecting Ryzen 1000 processors. Kyriakos Economou, co-founder of security research firm ZeroPeril, published a report last week that said non-privileged users could exploit the driver to access the sensitive information stored in memory, according to The Record. The PSP works with the operating system to store sensitive information in secured parts of memory, and it’s usually only accessible by administrators. The vulnerability ( CVE-2021-26333) exists in AMD’s Platform Security Processor (PSP) chipset driver.

In a report published last week, cybersecurity researchers disclosed a vulnerability in the driver that would allow attackers to steal sensitive information like passwords, and it impacts all Ryzen processors, as well as several previous AMD generations. AMD released a new chipset driver in August that patched “critical security flaws,” but it didn’t mention which vulnerabilities the patch worked for.
