AMD has rolled out the fix for the 'Sinkclose' Vulnerability potentially affecting millions of Systems running on AMD Ryzen & EPYC CPUs. The   'Sinkclose' Vulnerability enables the hackers to take control of the system and affects the Master Boot record of the system. This Vulnerability works like a  "bootkit" type of malware targeting the Master Boot Record of the system. It can even evade antivirus software and remains invisible to the operating system, which makes 'Sinkclose' Vulnerability very serious for the users of these CPUs.

The Sinkclose' Vulnerability is affecting millions of computers running on AMD Ryzen & EPYC CPUs. Attackers can take control of the system and copy the data & perform code Insertions into the system.

This bug is not a new bug but remained in the system for more than a decade. Now the individuals from the security firm IOActive revealed this bug at the Defcon hacker conference. This vulnerability is said to be present in the system for more than a decade which potentially provides a backdoor for possible attack. This bug is affecting AMD Ryzen & EPYC CPUs.

What is Sinkclose Vulnerability?

According to the media reports the Sinkclose Vulnerability allows the hackers to attack systems and run malicious code on the systems running AMD's CPUs. It can also affect the master boot record of the system and make the system vulnerable to data theft.

Hackers are able to obtain the "deep access to an AMD-based PC or server" to insert the code into the system. Hackers are utilizing the malware called bootkit, which is so powerful that it is not detected by any anti-virus or the operating system. This is one of the big security issues for the systems running on AMD's CPUs. 

Users of AMD's CPUs can connect to their system physically and use the SPI Flash programmer to patch the system. AMD has acknowledged 'Sinkclose' Vulnerability and thanked the researchers.

AMD has already released a new security bulletin addressing the potential vulnerability. Company also released fixes for the CPUs, which can be installed to address the issue. According to the reports, AMD has also identified the core issue.

In order to protect against Sinkclose Vulnerability, users should install the available patches on their system by downloading from the official website of AMD. This risk seems low for the average users but all the users of AMD processors should go ahead and update their system with the latest patches.

Patching the system with the latest patched release by AMD and their system manufacturer will help users in protecting their systems from potential security breach and data hack.
