CVE-2026-14684

A flaw has been found in HdrHistogram up to 2.2.2. This affects the function org.HdrHistogram.AbstractHistogram.decodeFromByteBuffer of the file src/main/java/org/HdrHistogram/AbstractHistogram.java. This manipulation of the argument numberOfSignificantValueDigits causes uncontrolled memory allocation. The attack can only be executed locally. The exploit has been published and may be used. The actual existence of this vulnerability is currently in question. This issue is disputed due to the potential lack of crossing of security boundaries and the pre-requisites for a successful attack.
