Multiples vulnérabilités dans le noyau Linux de Red Hat (04 septembre 2026)
De multiples vulnérabilités ont été découvertes dans le noyau Linux de Red Hat. Certaines d'entre elles permettent à un attaquant de provoquer une exécution de code arbitraire, une élévation de privilèges et un déni de service à distance.
CSIRTS triage
- What
- Multiple vulnerabilities in Red Hat Linux Kernel allow arbitrary code execution, privilege escalation, and remote denial of service.
- Who is affected
- Red Hat systems running affected kernel versions.
- Urgency
- Critical priority; remote code execution and privilege escalation require urgent remediation.
- Action
- Apply Red Hat kernel security updates addressing CVE-2026-68480, CVE-2026-64268, CVE-2026-74581, CVE-2026-72130, CVE-2026-53399, CVE-2026-53185, CVE-2026-53391, and CVE-2026-68086.

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-2026-684800.23% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 14% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-642680.71% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 51% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745810.40% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 33% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-721300.75% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 52% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-533990.54% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 44% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-531850.10% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
