CVE-2026-85445
MOOS-IvP through 24.8.1 contains a denial of service vulnerability in the Demuxer::addMuxPacket() function that trusts the packet count declared in mux headers without validation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
MOOS-IvP through 24.8.1 contains a denial of service vulnerability in the Demuxer::addMuxPacket() function that trusts the packet count declared in mux headers without validation. Attackers can declare arbitrarily large packet counts to trigger unbounded memory allocation, exhausting system resources and causing service unavailability.
