svxlink: svxlink: Unvalidated audio length and exposed transceiver control in remotetrx

In the Trivy database since at least 24 Oct 2026, 07:11 UTCWhen it arrived before that build is not recorded.

Severity by source

No source gives a CVSS score.

Trivy's own label is CRITICAL. Rated critical by Red Hat.

Description

A flaw was found in svxlink's remotetrx NetUplink component. An unvalidated audio length field enables an out-of-bounds read, and when AUTH_KEY is not set, transceiver control functions are exposed to unauthenticated remote access. This allows unauthorized control of radio hardware connected to the svxlink system.
