Last modified

CVE-2021-26410 is a low-severity vulnerability rated 1.8/10 on the CVSS scale. Improper syscall input validation in ASP (AMD Secure Processor) may force the kernel into reading syscall parameter values from its own memory space allowing an attacker to infer the contents of the kernel memory leading to potential information disclosure.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
