CVE-2026-45682: CWE-401: Missing Release of Memory after Effective Lifetime in open-telemetry opentelemetry-ebpf-instrumentation
CVE-2026-45682 is a medium severity vulnerability in open-telemetry's opentelemetry-ebpf-instrumentation prior to version 0. 9. 0. The issue involves a memory leak caused by the custom CappedConcurrentHashMap used for Java TLS state tracking, which fails to remove keys from its insertion-order queue when entries are deleted. This leads to unbounded growth of the queue and eventual heap memory exhaustion in long-running JVMs with frequent connection churn. The vulnerability has been patched in version 0. 9. 0.
AI Analysis
Technical Summary
OpenTelemetry eBPF Instrumentation versions before 0.9.0 contain a memory management flaw where the CappedConcurrentHashMap does not properly remove keys from its insertion-order queue upon entry deletion. This results in a memory leak that can exhaust heap memory in long-running instrumented JVMs experiencing repeated connection churn. The issue is addressed in version 0.9.0 of the product.
Potential Impact
The vulnerability causes heap memory exhaustion in affected JVMs, potentially leading to application crashes or degraded performance. There is no impact on confidentiality or integrity, only availability is affected. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade to opentelemetry-ebpf-instrumentation version 0.9.0 or later, where this memory leak issue has been fixed. Patch status is confirmed by the vendor advisory indicating the issue is resolved in version 0.9.0.
