Lifecycle Timeline
1DescriptionCVE.org
A vulnerability has been found in HdrHistogram up to 2.2.2. This vulnerability affects the function recordValueWithCount of the file src/main/java/org/HdrHistogram/AbstractHistogram.java of the component AbstractHistogram. Such manipulation of the argument Count leads to state issue. The attack can only be performed from a local environment. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
State corruption in HdrHistogram up to version 2.2.2 allows a local, low-privileged attacker to manipulate the Count argument of the recordValueWithCount function in AbstractHistogram.java, resulting in low-integrity corruption of histogram state. The flaw affects the core metrics-recording logic of this Java library. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the host running the JVM application that uses HdrHistogram. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The real-world risk of this vulnerability is very low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker with low OS-level privileges on a host running a JVM application that embeds HdrHistogram calls recordValueWithCount with a crafted Count argument, causing the AbstractHistogram object to enter a corrupted state. The public proof-of-concept demonstrates this manipulation, meaning the technique is already documented and reproducible. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
