In Bouncy Castle for Java before 1.85, HSS public-key level count unbounded, enabling huge allocation on verify. (CVE-2026-58060)
Bouncy Castle for Java versions before 1.85 have an unbounded HSS public-key level count, which can lead to excessive memory allocation during verification. This vulnerability also affects Bouncy Castle for Java LTS versions before 2.73.12 and Bouncy Castle for Java FIPS versions before 2.0.2 (2.0.X series) and 2.1.3 (2.1.X series).
AI Analysis
Technical Summary
The vulnerability in Bouncy Castle for Java prior to version 1.85 involves an unbounded count of HSS public-key levels. This flaw allows an attacker to trigger huge memory allocations during the verification process, potentially leading to resource exhaustion. The issue similarly affects Bouncy Castle for Java LTS before 2.73.12 and Bouncy Castle for Java FIPS before versions 2.0.2 and 2.1.3 in their respective series. No patch links are provided in the data, and no known exploits are reported in the wild.
Potential Impact
This vulnerability can cause excessive memory allocation during HSS public-key verification, which may lead to denial of service due to resource exhaustion. There is no indication of privilege escalation or data compromise from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor vendor communications for updates and consider limiting input sizes or applying other resource controls if possible.
