DescriptionCVE.org

A vulnerability was found in HdrHistogram up to 2.2.2. This issue affects the function org.HdrHistogram.DoubleHistogram.recordValue of the file src/main/java/org/HdrHistogram/DoubleHistogram.java of the component Range Check. Performing a manipulation results in incorrect comparison. The attack is only possible with local access. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Incorrect comparison in HdrHistogram's DoubleHistogram.recordValue() range check allows a local, low-privileged attacker to manipulate histogram integrity by recording out-of-range values that bypass the bounds check. Versions up to and including 2.2.2 are affected. …

Vulnerability AssessmentAI

Exploitation Exploitation requires local access to the system or process where the HdrHistogram library is in use - remote exploitation is not possible per AV:L. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N, score 4.8) consistently characterizes this as a low-severity, local-only integrity issue requiring low privileges. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local user or a process running with low privileges on a shared JVM application host crafts a specific floating-point value that passes the flawed range comparison inside DoubleHistogram.recordValue(). When the application (e.g., a Kafka broker or latency monitoring service) records this value, the histogram's internal state is corrupted, causing reported latency percentiles or throughput metrics to be skewed or incorrect. …
Remediation No vendor-released patch identified at time of analysis - the project maintainer had not responded to the GitHub issue report as of disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.
