Critical 'Sinkclose' Vulnerability Found in AMD Processors Since 2006

Security researchers reveal a severe flaw impacting millions of AMD CPUs, with potential for undetectable malware installation.

The 'Sinkclose' vulnerability affects nearly all AMD processors released since 2006, including EPYC and Ryzen models.
Exploiting the flaw requires kernel-level access, making it difficult but not impossible for attackers to execute.
Successful exploitation allows attackers to install undetectable bootkits, potentially requiring hardware replacement to remove.
AMD has issued mitigations for some affected processors, with more updates expected soon.
The vulnerability remained undetected for almost two decades, with no known instances of exploitation to date.
