Improper Syscall Input Validation in AMD Secure Processor (ASP) Enables Kernel Memory Disclosure
CVE-2021-26410 Published on February 10, 2026

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.

NVD

Weakness Type

Untrusted Pointer Dereference

The program obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.
