Detailsinfo

A vulnerability was found in open-telemetry opentelemetry-ebpf-instrumentation up to 0.8.x. It has been rated as problematic. This issue affects an unknown functionality. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. The summary by CVE is:

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the custom CappedConcurrentHashMap introduced for Java TLS state tracking never removes keys from its insertion-order queue when entries are deleted. In long-running instrumented JVMs, repeated connection churn can therefore grow the queue without bound and exhaust heap memory. This issue has been patched in version 0.9.0.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-45682 since 05/12/2026. The exploitation is known to be difficult. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.
