CVE-2026-87823

zstd-jni (Java JNI binding for Zstandard compression) versions 1.1.1 through 1.5.7-13 are vulnerable to an out-of-bounds read caused by 32-bit signed bounds checks in three direct-ByteBuffer frame-size native methods. An attacker can supply negative offset values near Integer.MIN_VALUE , causing ...

CVE-2026-87823 zstd-jni 1.1.1 through 1.5.7-13 Out-of-Bounds Read via Direct ByteBuffer Frame-Size Methods
