HPE Security Advisory
Published Date: June 10, 2026
Advisory Summary
Hewlett Packard Enterprise has released an important security bulletin (HPESBHF05057 rev.1) addressing a vulnerability affecting the HPE RL300 server line powered by Arm processors. The issue involves the potential for local attackers to disclose privileged information, posing a risk to confidential data residing on affected systems.
This vulnerability is particularly noteworthy due to its nature of local privilege information exposure, which could be exploited by attackers with access to the server to escalate their insight into sensitive system details. HPE urges all users running RL300 servers with Arm architecture to apply the recommended patches and updates immediately to mitigate this risk.
Given the critical infrastructure role these servers play, ensuring prompt remediation is crucial to maintaining operational security and data integrity. IT administrators should review the advisory carefully and prioritize the installation of security updates in their environment.
- Verify if your deployment includes HPE RL300 servers running on Arm processors.
- Apply the security patches provided by HPE without delay.
- Monitor systems for any unusual activity indicative of exploitation attempts.
