CVE-2026-14686
Description
A flaw was found in HdrHistogram. This vulnerability affects the DoubleHistogram.recordValue function, which is part of the Range Check component. A local attacker can exploit this flaw by performing a specific manipulation, leading to an incorrect comparison of values. This issue primarily impacts data integrity.
Statement
Low: This HdrHistogram flaw enables a local attacker to manipulate data, resulting in incorrect value comparisons and a data integrity impact. The requirement for local system access significantly reduces the overall exposure and risk for Red Hat products.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Application Data; Execute Unauthorized Code or Commands
An attacker could modify the structure of the message or data being sent to the downstream component, possibly injecting commands.
Availability
Technical Impact: DoS: Resource Consumption (Other)
in some contexts, a negative value could lead to resource consumption.
Confidentiality,Integrity
Technical Impact: Modify Memory; Read Memory
If a negative value is used to access memory, buffers, or other indexable structures, it could access memory outside the bounds of the buffer.
