CVE-2026-90560: Out-of-bounds Read in luben zstd-jni
zstd-jni versions 1.2.0 through 1.5.7-13 contain an out-of-bounds read vulnerability in the ZstdDictDecompress constructor because offset and length arguments are never validated against the dictionary array bounds. Attackers can supply arbitrary offset or length values to read memory past the end of the supplied array, potentially causing JVM termination.
AI Analysis
Technical Summary
CVE-2026-90560 is an out-of-bounds read vulnerability in the zstd-jni library maintained by luben. Specifically, in versions 1.2.0 through 1.5.7-13, the ZstdDictDecompress constructor does not validate offset and length arguments against the dictionary array bounds. This allows an attacker to supply arbitrary offset or length values, causing the program to read memory beyond the intended buffer. The vulnerability can cause the Java Virtual Machine (JVM) to terminate unexpectedly.
Potential Impact
The vulnerability allows an attacker to cause an out-of-bounds read, which can lead to JVM termination. This results in denial of service but does not indicate code execution or data corruption based on the provided information.
Mitigation Recommendations
A fixed version is available starting from 1.5.7-14. Users should upgrade to version 1.5.7-14 or later to remediate this vulnerability. No other mitigation steps are indicated.
