CVE-2026-15562: Integer Overflow or Wraparound in Red Hat Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7
CVE-2026-15562 is a denial of service vulnerability in Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7. It involves an integer overflow or wraparound flaw in the jboss-remoting component. A remote unauthenticated attacker able to reach specific ports and complete a jboss-remoting handshake can cause out-of-memory errors that degrade server-wide request handling.
AI Analysis
Technical Summary
This vulnerability affects the jboss-remoting component of Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7. An integer overflow or wraparound flaw allows a remote unauthenticated attacker who can access ports 8080, 9990, or 4447 and complete an Upgrade: jboss-remoting handshake to trigger out-of-memory (OOM) errors. These OOM errors degrade the server's ability to handle requests, resulting in denial of service conditions across the application platform.
Potential Impact
The impact is denial of service (DoS) caused by out-of-memory errors that affect the entire server's request processing capabilities. There is no confidentiality or integrity impact reported. The vulnerability can be exploited remotely without authentication.
Mitigation Recommendations
A security update is available in Red Hat JBoss Enterprise Application Platform 7.4.25 that addresses this vulnerability. Users should upgrade to version 7.4.25 or later to remediate the issue. Refer to the Red Hat advisory RHSA-2026:53644 for official patch details and instructions.
