CVE-2026-87823 (GCVE-0-2026-87823)

Vulnerability from cvelistv5 – Published: 2026-09-09 14:32 – Updated: 2026-09-09 16:13

Title

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

Summary

zstd-jni before 1.5.7-14 performs 32-bit signed bounds checks on three direct-ByteBuffer frame-size native methods, allowing out-of-bounds memory reads via negative or overflowing offsets. Attackers can supply negative offset values near Integer.MIN_VALUE to read unmapped memory, causing JVM termination or extracting arbitrary frame size data from unintended memory locations.

Severity

8.8 (High)

CVE-2026-87825 (GCVE-0-2026-87825)

Vulnerability from cvelistv5 – Published: 2026-09-09 14:32 – Updated: 2026-09-14 13:35

Title

zstd-jni 1.3.8-4 through 1.5.7-13 Use-After-Free of Compression and Decompression Dictionaries

Summary

zstd-jni before 1.5.7-14 contains a use-after-free vulnerability where streams and contexts hold a dictionary's shared lock only during the load call, allowing the dictionary to be closed while still referenced. Attackers can close a dictionary after associating it with a stream or context, causing subsequent read or write operations to access freed native memory, resulting in silent data corruption or JVM crashes.
