Background
OpenSSH is a widely used implementation of the SSH (Secure Shell) protocol, providing secure communication over unsecured networks. It is essential for remote server management and file transfers. The OpenSSH suite includes various components such as the SSH client, server, and related utilities, making it a critical component in many Linux and UNIX-based systems. This vulnerability affects multiple OpenSSH packages in AlmaLinux 10, potentially exposing systems to brute-force attacks due to insufficient authentication delay.
Vulnerability Detail
The vulnerability identified as CVE-2026-60001 allows attackers to perform brute-force attacks on OpenSSH due to a lack of adequate authentication delay. This weakness can lead to unauthorized access to systems, compromising sensitive data and potentially allowing further exploitation of the affected systems. The issue arises from the way OpenSSH handles authentication attempts, failing to impose sufficient delays between successive login attempts, which could be exploited by attackers to guess passwords more rapidly.
How To Fix
Minimum fixed version
9.9p1-28.el10_2.alma.1
This is the first release that contains the fix.

Workaround
As a temporary workaround, you can implement rate limiting on authentication attempts or configure fail2ban to block IP addresses after a certain number of failed login attempts. This can help mitigate the risk of brute-force attacks until the packages are updated.
Conclusion
The OpenSSH vulnerability CVE-2026-60001 poses a moderate risk due to the potential for brute-force attacks. It is crucial to update the affected packages to the latest patched version to mitigate this risk. Implementing temporary workarounds can also help protect your systems until updates are applied.
