CVE-2026-45676

CVE-2026-45676 affects OpenTelemetry eBPF Instrumentation (OBI). Before version 0.9.0, OBI’s replacement ELF parser trusts section offsets, counts, and string offsets from the executable, allowing a crafted local ELF to trigger invalid dereferences or out-of-bounds slicing in the parser. The vuln...

CVE-2026-45682 OpenTelemetry eBPF Instrumentation: CappedConcurrentHashMap leaks keys after removals

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...

CVE-2026-45682

OpenTelemetry eBPF Instrumentation CVE-2026-45682 describes a leak in CappedConcurrentHashMap used for Java TLS state tracking: when entries are deleted, keys are not removed from the insertion-order queue, allowing the queue to grow in long-running instrumented JVMs. The issue causes heap exhaus...

OpenTelemetry eBPF Instrumentation 安全漏洞

OpenTelemetry eBPF Instrumentation is an open-source eBPF-based lightweight telemetry data collection tool developed by OpenTelemetry. Versions of OpenTelemetry eBPF Instrumentation from 0.1.0 to 0.9.0 contained security vulnerabilities. These vulnerabilities stemmed from malformed MongoDB line...

GHSA-89C6-VPCJ-7VJ4 OpenTelemetry eBPF Instrumentation: Unbounded BPF internal metrics replay can exhaust CPU

Summary OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the metrics exporter to spend excessive CPU time in a tight loop every collection interval. Details The vulnerable loop is in...

GHSA-8RRQ-WCG8-CV5Q OpenTelemetry eBPF Instrumentation: Redis error text is exported in span status messages

Summary OBI exports raw Redis error text as the span status message. Because Redis error replies can contain attacker-controlled or sensitive values, this behavior can exfiltrate tokens, PII, or other confidential input into telemetry backends and inject untrusted text into downstream analysis...

OpenTelemetry eBPF Instrumentation: Unsafe fastelf parsing allows malformed ELF to crash agent

Summary OBI's replacement ELF parser trusts section offsets, counts, and string offsets from the executable file. A crafted local ELF can make OBI dereference invalid section pointers or slice past string tables, causing the agent to panic while determining the process language. Details...

CVE-2026-41433

OpenTelemetry eBPF Instrumentation (OpenTelemetry OBI) has a local impact flaw in the Java agent injection path for versions 0.4.0–0.7.x (before 0.8.0). A compromised Java workload can cause arbitrary host file overwrites when Java injection is enabled and OBI runs with elevated privileges. The r...

GHSA-8GMG-3W2Q-65F4 OpenTelemetry eBPF Instrumentation: Privileged Java agent injection allows arbitrary host file overwrite via untrusted TMPDIR

Summary A flaw in the Java agent injection path allows a local attacker controlling a Java workload to overwrite arbitrary host files when Java injection is enabled and OBI is running with elevated privileges. The injector trusted TMPDIR from the target process and used unsafe file creation...
