chore: upload signed secmon
(cherry picked from commit 64698d0d844e3322eca435beaae3df602aa08b10)
What changed, and why it matters
This commit replaces a binary file called secmon.bin for the T3W1 hardware model with a 'signed' version. The actual contents of the binary file are not shown in the diff, so there is no visible code change to review. The commit message describes it as a routine chore to upload a signed secure monitor binary. No security relevance is stated, and no independent researcher or incident is mentioned.
Treat this commit as unreviewable from a security standpoint because it is an opaque binary blob. If assessing risk, request the vendor to provide the corresponding source diff, build reproducibility artifacts, changelog entry, and signature verification instructions for the secure monitor. Do not score it as a vulnerability or security fix without additional evidence.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff only shows that core/embed/models/T3W1/secmon/secmon.bin changed as a binary blob. No source code, symbols, hashes, signatures, or functional description are included in the commit or references. It is impossible from the supplied materials to determine what the secure monitor does, what changed between the two blobs, or whether the change fixes or introduces any security issue. The ‘signed’ descriptor in the title only indicates the blob is cryptographically signed, which is a normal release artifact property.
