CVE-2021-22887

CVE-2021-22887 covers a BIOS‑level vulnerability in Pulse Secure PSA‑Series hardware (PSA5000/PSA7000). The root issue is in BIOS firmware that could be compromised as part of an attack chain after an initial device compromise. The practical impact is BIOS integrity exposure, with no public explo...

CVE-2021-3418

If certificates that signed grub are installed into db, grub can be booted directly. It will then boot any kernel without signature validation. The booted kernel will think it was booted in secureboot mode and will implement lockdown, yet it could have been tampered. This flaw is a reintroduction...

Vulnerabilities fixed in Intel BIOS

Intel has fixed vulnerabilities in the BIOS which is used along with specific Xeon and Atom processors. The vulnerabilities enable a locally authenticated malicious person to opportunity to obtain elevated privileges. The malicious party needs physical access to the vulnerable machine to do so...
