AI Analysis
Technical Summary
CVE-2026-3505 is an uncontrolled resource consumption vulnerability (CWE-770) in the BC-JAVA library by Legion of the Bouncy Castle Inc., specifically in the bcpg modules. The vulnerability arises from allocation of resources without limits or throttling in AEAD encryption-related Java classes (AEADEncDataPacket.Java, BcAEADUtil.Java, JceAEADUtil.Java, OperatorHelper.Java). Affected versions include BC-JAVA from 1.74 before 1.80.2, from 1.81 before 1.81.1, and from 1.82 before 1.84. The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, no privileges or user interaction required, and high impact on availability. Red Hat has published multiple advisories and errata referencing this CVE and providing security updates for their JBoss Enterprise Application Platform 8.1 on RHEL 8, which includes fixes for this vulnerability. However, the vendor advisory content does not explicitly state the remediation level or patch availability for BC-JAVA itself, though the presence of errata suggests updates are available in Red Hat's distribution.
Potential Impact
The vulnerability allows an attacker to cause uncontrolled resource consumption on affected systems using BC-JAVA, potentially leading to denial of service conditions due to exhaustion of system resources. The high CVSS score reflects significant impact on availability with no required privileges or user interaction, and exploitable remotely over the network.
Mitigation Recommendations
Red Hat has issued security advisories and errata that include updates addressing CVE-2026-3505 for their JBoss Enterprise Application Platform 8.1 on RHEL 8. Users of Red Hat distributions should apply these security updates as per Red Hat's guidance. Since the vendor advisory does not explicitly state the remediation level or patch availability for BC-JAVA outside of Red Hat's packages, users of BC-JAVA should monitor the official Legion of the Bouncy Castle Inc. channels for patches or updates. Patch status is not yet confirmed for BC-JAVA upstream — check the vendor advisory for current remediation guidance.
