Linux Kernel ↗
Summary iPlain-English security verdict for Linux Kernel, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
Linux Kernel currently scores 0/100 — critical, with active exploitation. 6 of its known vulnerabilities are being actively exploited in the wild (CISA KEV), including CVE-2026-31431. The latest supported release is 7.1.5. Upgrade immediately and review your exposure to the actively-exploited CVEs below. Note: this product is assessed at the product level on recent (365-day) activity rather than an exact per-version match, so it is never marked a confident "healthy".
Disclosure trend iNew CVEs published for Linux Kernel each year (NVD). A higher bar means more disclosures that year — more scrutiny, not necessarily less safe.
Patch priority — what to act on iThe issues to fix first — actively exploited (CISA KEV) first, then by exploitation probability (EPSS), then severity. Each row's "→ fixed in" is the earliest version that patches it; "see advisory" means no fixed version is published.
Most urgent first — actively exploited, then likeliest to be exploited.
