CVE-2026-85442
Unauthenticated packet-length parsing allows memory-exhaustion DoS in core-moos.
Is CVE-2026-85442 being exploited?
Not confirmed. CVE-2026-85442 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.41% probability of exploitation in the next 30 days.
How severe is CVE-2026-85442?
CVE-2026-85442 is rated High. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-85442?
Yes. A fix has been recorded for CVE-2026-85442. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-85442 affect?
CVE-2026-85442 affects core-moos (MOOS) <= 10.4.0, MOOSDB, MOOS-based systems using CMOOSCommPkt. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-85442?
Apply upstream patch or update core-moos to the fixed commit/version immediately.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Unauthenticated remote attacker can declare huge packet lengths to trigger unbounded allocation and exhaust server memory, causing denial of service (pre-auth).
Immediate action required
- affected<= 10.4.0
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.
