When handling ICMP echo requests, the reply length is not updated to match the actual data received from the host. Under specific conditions where the normal ICMP socket is unavailable, this length mismatch causes the host's real IP address to be leaked to the guest in the echo reply, breaking the NAT isolation that user-mode networking is expected to provide.","categories":["Operating systems"],"product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115449","source_modified_at":"2026-10-23T15:00:22.267Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115449","source_modified_at":"2026-10-23T15:00:22.267Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115449","source_modified_at":"2026-10-23T15:00:22.267Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115449","source_modified_at":"2026-10-23T15:00:22.267Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat OpenShift Container Platform 4","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":3.5,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00226,"percentile":0.12615,"score_date":"2026-10-23"},"published_at":"2026-10-22T21:20:56.855Z","modified_at":"2026-10-23T15:00:22.267Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115449","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T15:00:22.267Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-115449","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-115449","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2558916","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-23T14:48:36.883093Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T15:00:22.267Z","content_hash":"03d24ec38d1440b376c83d160e90a16a1311fab2b705f5867eccb0ba92d76e0b"}}
