golang-github-tillitis-tkeyclient: Tillitis TKey Client package is a Go package for a TKey client
CVE-2026-32953 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-32953, released March 20, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Tillitis TKey Client package is a Go package for a TKey client. Versions 1.2.0 and below contain a critical bug in the tkeyclient Go module which causes 1 out of every 256 User Supplied Secrets (USS) to be silently ignored, producing the same Compound Device Identifier (CDI)—and thus the same key material—as if no USS is provided. This happens because a buffer index error overwrites the USS-enabled boolean with the first byte of the USS digest, so any USS whose hash starts with 0x00 is effectively discarded. This issue has been fixed in version 1.3.0. Users unable to upgrade immediately should switch to a USS whose hash does not begin with a zero byte.
