Alta Video — 2052: Potential out-of-band read in golang.org/x/crypto/ssh/agent

Release Date

07 Apr 2026.

Overview

A vulnerability was identified in the golang.org/x/crypto/ssh/agent package related to the processing of new identity requests. Specifically, the SSH agent servers did not validate the size of messages, potentially leading to an out-of-bounds read. This could cause the program to panic if a malformed message was received. The impact of such an attack is considered lower in our system as the SSH process is automatically restarted and it runs in its own process.
