CVE-2026-45683
LowCVSS 3.8Exploitation Probability (EPSS)
Low risk7th percentile - higher than 7% of all known CVEs
Summary
OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the Java TLS ioctl probe reads user-controlled ioctl pointers with bpf_probe_read instead of bpf_probe_read_user. An instrumented local process can therefore point OBI at kernel memory and cause that memory to be copied into telemetry.
Risk Assessment
A local attacker can read kernel memory, potentially leading to leakage of sensitive system data or privilege escalation.
Recommendation
Update OpenTelemetry eBPF Instrumentation to version 0.9.0 or later.
