CVE-2026-45686— OpenTelemetry eBPF Instrumentation 输入验证错误漏洞

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 memcached storage commands such as set, add, replace, append, prepend, or cas, OBI accepts extremely large <bytes> values and adds the payload delimiter length without checking for overflow. A crafted request with <bytes> set to math.MaxInt or math.MaxInt-1 causes the computed payload length to wrap negative and triggers a runtime panic in LargeBufferReader.Peek. This issue has been patched in version 0.9.0.

OpenTelemetry eBPF Instrumentation 输入验证错误漏洞

OpenTelemetry eBPF Instrumentation是OpenTelemetry开源的一个基于eBPF的轻量级遥测数据采集工具。 OpenTelemetry eBPF Instrumentation 0.7.0版本至0.9.0之前版本存在输入验证错误漏洞，该漏洞源于memcached文本协议解析器中存在远程可达的整数溢出，可能导致崩溃OBI进程并造成拒绝服务。
