CVE-2026-64304

A flaw was found in the Linux kernel's QAT (QuickAssist Technology) crypto module. This vulnerability occurs in the RSA key parser when handling CRT (Chinese Remainder Theorem) components. An underflow can happen during a memory copy operation if an RSA CRT component is larger than its allocated buffer, leading to memory corruption. This could potentially allow an attacker to cause system instability or execute arbitrary code.
