CVE-2023-47855: Improper input validation in some Intel(R) TDX module software before version 1.5.05.46.698 may allow a privileged user to potentially enabl
Noroxi assessment
Priority: Monitor (action score 26/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.37% (FIRST EPSS).
- Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: intel-microcode (Debian:12) 3.20240514.1~deb12u1; intel-microcode (Debian:13) 3.20240514.1; ucode-intel (openSUSE:Leap Micro 5.3) 20240514-150200.41.1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to intel-microcode (Debian:12) 3.20240514.1~deb12u1; intel-microcode (Debian:13) 3.20240514.1; ucode-intel (openSUSE:Leap Micro 5.3) 20240514-150200.41.1 or later.
