Android OS
Auto-added after CISA flagged Android OS as actively exploited (KEV catalog). Version and lifecycle mapping is pending review, so this is assessed at the product level and is never reported as a confident "healthy".
Known exploited vulnerability
CISA's Known Exploited Vulnerabilities (KEV) catalog flagged Android OS (Android) as exploited in the wild — that's why IsItPatched started tracking it. The vulnerability that triggered it:
CVE-2011-1823 ↗ view on NVD
Per-version vulnerability and lifecycle data for Android OS is still being mapped, so no health score is shown yet. Treat it as urgent: identify the exact version you run and confirm it against Android's advisory, then move to a patched, supported release.
Summary iPlain-English security verdict for Android OS, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
Android OS is on CISA's Known Exploited Vulnerabilities (KEV) catalog — it was confirmed under active attack in the wild, which is why CVE-2011-1823 led IsItPatched to start tracking Android's Android OS. Its per-version vulnerability and lifecycle data is still being mapped, so no health score is shown yet. Treat Android OS as urgent: identify the exact version you run and confirm it against Android's security advisory, then move to a patched, supported release.
Disclosure trend iNew CVEs published for Android OS 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.
