CVE-2026-89046: Out-of-bounds Read in luben zstd-jni
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.
AI Analysis
Technical Summary
CVE-2026-89046 affects zstd-jni versions from 1.5.5-6 up to but not including 1.5.7-14. The vulnerability is an out-of-bounds read in the native frame-header parser triggered by supplying negative offset values to the Zstd.getFrameContentSize method. The lack of validation on negative srcPosition arguments allows attackers to bypass bounds checks, resulting in memory reads outside the intended buffer. This can cause information disclosure or cause the Java Virtual Machine to crash.
Potential Impact
Successful exploitation can lead to information disclosure or JVM crashes due to out-of-bounds memory reads. The vulnerability does not require privileges or user interaction and can be exploited remotely over the network, making it a high-severity risk.
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. Patch status is confirmed by the affected version range indicating the fix at 1.5.7-14.
