Multiple vulnerabilities in Red Hat Linux kernel (August 07, 2026)
Multiple vulnerabilities have been discovered in Red Hat Linux kernel. Some of them allow an attacker to cause arbitrary code execution, privilege escalation and remote denial of service.
CSIRTS triage
- What
- Multiple kernel vulnerabilities enable arbitrary code execution, privilege escalation, and remote denial of service.
- Who is affected
- Systems running affected Red Hat Linux kernel versions.
- Urgency
- Critical; remote code execution via kernel vulnerabilities is highest priority.
- Action
- Apply Red Hat kernel security updates immediately; prioritize systems exposed to untrusted networks.

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-2026-645310.38% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 31% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-638070.14% 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-2026-231990.09% 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-2025-400260.16% 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-2026-317870.18% 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-2026-463030.31% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 24% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-529930.37% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 30% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-461130.15% 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-2026-316920.12% 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-2026-434500.13% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 3% of all EPSS-scored CVEs.
