criticalCVSS 9.8covered by 20 sourcesfirst seen 2026-07-19

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 kernel flaws including NTFS file system out-of-bounds read, AMD processor floating point unit data exposure, and AMD Zen 2 operation cache isolation failure.
Who is affected: Systems running affected Linux kernel versions; local attackers on systems with NTFS mounted or AMD processors.
Urgency: Moderate to high — local attackers can gain privilege escalation and information disclosure; apply patches promptly.
Action: Apply kernel security updates provided by distribution maintainer.
