CVE-2026-3505 is an uncontrolled resource-consumption vulnerability in the Bouncy Castle BC-JAVA bcpg PGP modules. PGP AEAD packet processing permits an unbounded chunk size, allowing resource allocation before packet authentication completes. The issue affects BC-JAVA versions from 1.74 before 1.80.2, from 1.81 before 1.81.1, and from 1.82 before 1.84.
