Summary
A flaw was found in zstd-jni. This out-of-bounds read vulnerability in the Zstd.getFrameContentSize function occurs because it fails to validate negative srcPosition arguments.
A remote attacker can supply negative offset values, bypassing bounds checks and accessing the native frame-header parser. This can lead to out-of-bounds memory reads, resulting in information disclosure or a Java Virtual Machine (JVM) crash.
This may disclose native memory or cause a JVM crash. Red Hat severity: Important — CVSS 8.2 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H).

Mitigation checklist
- Update to a product release containing zstd-jni 1.5.7-14 or later. Until updated, validate source positions and reject negative offsets before calling Zstd.getFrameContentSize. Do not pass attacker-controlled offsets to this method without validation.
