In Bouncy Castle for Java before 1.85, OER parser recurses without depth limit on self-referential IEEE 1609.2 schema. (CVE-2026-59645)
A vulnerability in Bouncy Castle for Java before version 1.85 allows the OER parser to recurse without a depth limit when processing a self-referential IEEE 1609.2 schema. This can lead to a denial of service due to resource exhaustion. The issue also affects Bouncy Castle for Java LTS before 2.73.12 and Bouncy Castle for Java FIPS before bcutil-fips 2.0.7 (2.0.X series) and 2.1.7 (2.1.X series).
AI Analysis
Technical Summary
CVE-2026-59645 describes a vulnerability in the OER parser component of Bouncy Castle for Java versions prior to 1.85. The parser does not impose a recursion depth limit when handling self-referential IEEE 1609.2 schemas, which can cause unbounded recursion. This flaw also affects Bouncy Castle for Java LTS versions before 2.73.12 and Bouncy Castle for Java FIPS versions before bcutil-fips 2.0.7 and 2.1.7 in their respective series. The vulnerability is classified under CWE-674 (Uncontrolled Recursion).
Potential Impact
The vulnerability can be exploited remotely without authentication and requires no user interaction. It does not impact confidentiality or integrity but can cause a denial of service by exhausting system resources due to uncontrolled recursion in the parser.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Users should monitor vendor communications for updates and apply patches once available.
