CVE-2025-47914

A flaw was found in the SSH Agent servers component (golang.org/x/crypto/ssh/agent). This vulnerability allows a remote attacker to cause a denial of service (DoS) by sending a specially crafted, malformed message during new identity requests. The server fails to validate the size of these messages, leading to an out-of-bounds read that can cause the program to panic and terminate.

This vulnerability is rated Moderate for Red Hat products. The golang.org/x/crypto/ssh/agent library, when used in SSH Agent servers, does not properly validate the size of messages during new identity requests. A specially crafted malformed message can lead to an out-of-bounds read, causing the program to panic and resulting in a denial of service.
