[UPDATE] [high] AMD Processor: Multiple vulnerabilities
An attacker can exploit multiple vulnerabilities in the AMD Processor to escalate privileges, execute arbitrary code—even with administrator rights—manipulate data, disclose confidential information, or cause a denial-of-service condition.
CSIRTS triage
- What

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-2021-263800.10% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2021-467470.10% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2022-238260.08% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 0% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2023-313160.10% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2024-140120.13% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 3% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2024-363150.14% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 3% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2024-363430.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 8% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2024-363450.11% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-00280.10% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
