CVE-2026-14682 is an excessive memory allocation vulnerability in Bouncy Castle Java products. The DefiniteLengthInputStream code path performs unbounded up-front allocation during a definite-length read. Crafted input can trigger excessive allocation and an out-of-memory condition, resulting in denial of service. Affected versions include Bouncy Castle for Java before 1.85, Java LTS before 2.73.12, BC-FJA 1.0.x before 1.0.2.7, 2.0.x before 2.0.2, and 2.1.x before 2.1.3, and bctls-fips before 1.0.24.
