- =============
- Old Microcode
- =============
- The kernel keeps a table of released microcode. Systems that had
- microcode older than this at boot will say "Vulnerable". This means
- that the system was vulnerable to some known CPU issue. It could be
- security or functional, the kernel does not know or care.
- You should update the CPU microcode to mitigate any exposure. This is
- usually accomplished by updating the files in
- /lib/firmware/intel-ucode/ via normal distribution updates. Intel also
- distributes these files in a github repo:
- https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files.git
- Just like all the other hardware vulnerabilities, exposure is
- determined at boot. Runtime microcode updates do not change the status
- of this vulnerability.
