Doc Text:	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.	Story Points:	---

Description OSIDB Bzimport 2026-09-10 17:52:32 UTC

zstd-jni versions 1.5.5-6 through 1.5.7-13 contain an out-of-bounds read vulnerability in Zstd.getFrameContentSize that fails to validate negative srcPosition arguments. Attackers can supply negative offset values that bypass bounds checks and reach the native frame-header parser, causing out-of-bounds memory reads that lead to information disclosure or JVM crashes.
