[UPDATE] [medium] AMD Processor: Multiple vulnerabilities

CSIRTS triage

What

Multiple vulnerabilities in AMD Processor and Dell BIOS allow privilege escalation, arbitrary code execution, and denial of service.

Who is affected

Systems running affected AMD Processor generations with vulnerable Dell BIOS firmware versions.

Urgency

Medium severity; local attacker access is required, but compromise leads to system takeover.

Action

Update Dell BIOS firmware to patch the Insyde UEFI vulnerabilities; apply AMD processor-level mitigations if available.

Exploitation outlook

EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.

• Low exploitation riskCVE-2023-205760.13% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 2% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2023-205770.16% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 5% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2023-205790.16% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2023-205870.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
