A bug affects the Linux kernel’s ksmbd NTLMv2 authentication and is known to crash the OS immediately in Linux-based systems.
CVE-2023-0210
Score elevated to 8.6 because EPSS predicts 72% probability of exploitation within the next 30 days (top 0.6% of all CVEs). NVD baseline CVSS 7.5 retained for reference. Confidence: see factors.
- High exploitation likelihood — EPSS 72%
