CVE-2026-85455
MOOS core-moos through 10.4.0 contains a buffer over-read vulnerability in CMOOSCommPkt where a four-byte packet triggers out-of-bounds memory access during deserialization.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
