{"id":"GHSA-f2r5-5m7w-p5cx","summary":"opentelemetry-ebpf-profiler: Unprivileged process can trigger a denial of service on the ebpf-profiler agent","details":"### Summary\n\nAn unprivileged process can easily trigger the `processPIDEvents` goroutine to be blocked indefinitely, preventing the goroutine from analyzing any new ELF file. The goroutine stays blocked in the `openat2` syscall forever and the profiler can no longer work properly, it is a denial of service.\n\n### Impact\n\nThe impact is limited to denial-of-service on the ebpf-profiler agent:\n- There has to be a malicious workload albeit unprivileged.\n- No exfiltration of data. No loss of data.\n\n###  Fix\n\nFixed in https://github.com/open-telemetry/opentelemetry-ebpf-profiler/commit/234b685cab31c2cb2f79e966caeab168bcc489e4.\n\nFix is part of [v.0.0.202622](https://github.com/open-telemetry/opentelemetry-ebpf-profiler/releases/tag/v0.0.202622).","aliases":["CVE-2026-48496","GO-2026-5343"],"modified":"2026-09-10T03:50:49.236007900Z","published":"2026-06-23T22:16:14Z","database_specific":{"github_reviewed_at":"2026-06-23T22:16:14Z","nvd_published_at":null,"cwe_ids":["CWE-770"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-ebpf-profiler/security/advisories/GHSA-f2r5-5m7w-p5cx"},{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-ebpf-profiler/commit/234b685cab31c2cb2f79e966caeab168bcc489e4"},{"type":"PACKAGE","url":"https://github.com/open-telemetry/opentelemetry-ebpf-profiler"},{"type":"WEB","url":"https://github.com/open-telemetry/opentelemetry-ebpf-profiler/releases/tag/v0.0.202622"}],"affected":[{"package":{"name":"go.opentelemetry.io/ebpf-profiler","ecosystem":"Go","purl":"pkg:golang/go.opentelemetry.io/ebpf-profiler"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.202527"},{"fixed":"0.0.202622"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-f2r5-5m7w-p5cx/GHSA-f2r5-5m7w-p5cx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
