"Linux Kernel and AMD Zen 2 CPUs Patched for 'Zenbleed' Vulnerability"
Originally Published 2 years ago — by Phoronix
The Linux kernel has received a patch to mitigate the "Zenbleed" vulnerability affecting older AMD CPUs, which manifests as a data corruption issue when executing VZEROUPPER under certain microarchitectural conditions. While the Linux kernel patch provides a mitigation, the most effective solution is to run the latest AMD processor microcode. The vulnerability was discovered by Tavis Ormandy from Google Information Security.
