CVE-2026-75371

Service interruption via cobs_decode integer handling

Published Aug 24, 2026 · Updated Aug 24, 2026

Integer handling in SpaceDot AcubeSAT OBC software commit eaf90ec allows physically proximate attackers to interrupt service via crafted UART input. The public record identifies cobs_decode as the affected locus but does not disclose the arithmetic operation, malformed byte sequence, or resulting failure mode. Direct UART access to the embedded OBC is required, and the reported consequence is limited to service interruption.
