CVE-2026-45683 OpenTelemetry eBPF Instrumentation: Java TLS ioctl kprobe allows kernel memory disclosure

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 bpfproberead instead of bpfprobereaduser. An instrumented local process can therefore point OBI at kerne...

CVE-2026-45683

OpenTelemetry eBPF Instrumentation (Java TLS ioctl) is affected prior to version 0.9.0. The vulnerability stems from the probe reading user-supplied ioctl pointers with bpf_probe_read instead of bpf_probe_read_user, enabling a local attacker to cause the kernel memory pointed to by user space to ...
