CVE-2026-87795

A flaw was found in zstd-jni. This vulnerability occurs due to insufficient validation of offset and length parameters within the ZstdDictCompress constructor. An attacker can exploit this by providing untrusted values, leading to an out-of-bounds memory read. This can result in the disclosure of...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read due to the ZstdDictCompressbyte dict, int offset, int length, int level constructor in ZstdDictCompress.java. An attacker can trigger a native heap read, crash the JVM, or leak adjacent memory by supplying a negative...
