Unauthenticated UDP allows message spoofing and DoS in MOOS pShare
Is CVE-2026-85430 being exploited?
Not confirmed. CVE-2026-85430 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-85430?
CVE-2026-85430 is rated High with a CVSS score of 8.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

What should I do about CVE-2026-85430?
Apply the patched commit/release and block pShare UDP ingress at network edge.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
