AMD won’t patch Sinkclose security bug on older Zen CPUs
2024-08-13 03:14

The bug allows malicious software and rogue privileged users with access to the operating system kernel to run code in System Management Mode, a highly privileged execution environment present in x86 processors from Intel and AMD. SinkClose is unique to AMD. SMM sits below the kernel and hypervisor, as well as applications, in that the management mode has unrestricted access to and control of the machine.
