CVE-2026-46136
De multiples vulnérabilités ont été découvertes dans le noyau Linux d'Ubuntu. Certaines d'entre elles permettent à un attaquant de provoquer une élévation de privilèges, un déni de service à distance et une atteinte à l'intégrité des données.
CSIRTS triage
- What
- Microarchitectural vulnerabilities in AMD processors and Linux kernel flaws affecting floating-point divider, operation cache isolation, and RDSEED entropy handling.
- Who is affected
- Raspberry Pi systems and those running affected AMD processors with vulnerable Linux kernels.
- Urgency
- Moderate; side-channel and privilege escalation vectors, mostly local exploitation required.
- Action
- Apply USN-8665-1 kernel security update for Raspberry Pi.
