CVE-2026-54712

OpenTelemetry Java Instrumentation provides OpenTelemetry auto-instrumentation and instrumentation libraries for Java. In versions prior to 2.27.0, the RMI context propagation payload reader limits the number of context entries but does not limit the aggregate size of the strings read from the...

CVE-2026-45676

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, 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...

CVE-2026-45684

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.7.0 to before version 0.9.0, OBI's log enricher mishandles writev buffers by reading only the first iovec entry but using the total ioviter.count as the copy length. When log...

CVE-2026-45686 OpenTelemetry eBPF Instrumentation: Memcached payload length overflow can crash OBI

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.7.0 to before version 0.9.0, a remotely reachable integer overflow in OBI's memcached text protocol parser can crash the OBI process and cause denial of service. When parsing...

CVE-2026-45685 OpenTelemetry eBPF Instrumentation: MongoDB parser panics on malformed wire messages

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.1.0 to before version 0.9.0, malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetr...

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...

OpenTelemetry eBPF Instrumentation: CPU-mismatch fallback uses 256-byte buffer with 8KB size

Summary The per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can read beyond the fallback buffer and leak adjacent memory into telemetry. Details...

PT-2026-41783

Name of the Vulnerable Software and Affected Versions OpenTelemetry eBPF Instrumentation versions prior to 0.9.0 Description The Postgres protocol parser incorrectly assumes that BIND message payloads contain a valid NUL-terminated portal name. When processing a crafted empty or unterminated...

CVE-2026-33701

OpenTelemetry Java instrumentation (opentelemetry-javaagent) contains an unsafe deserialization flaw in its RMI integration prior to version 2.26.1. If the agent is attached on a JDK 16 or earlier, and an RMI/JMX port is network-reachable with a gadget-chain–compatible library on the application ...

GHSA-H8W2-RV57-VC6F splunk-otel-javaagent: Unsafe deserialization in RMI instrumentation may lead to Remote Code Execution

In versions prior to 2.26.1, the RMI instrumentation registered a custom endpoint that deserialized incoming data without applying serialization filters. An attacker with network access to a JMX or RMI port on an instrumented JVM could exploit this to potentially achieve remote code execution. Al...
