{"schema":"threatline.record/2","record":{"id":"CVE-2026-116497","aliases":[],"summary":"Gssproxy: gssproxy: null pointer dereference in gssx_init_sec_context crashes daemon","details":"A NULL pointer dereference vulnerability was found in gssproxy. When a GSSX_INIT_SEC_CONTEXT request is received with the target_name field absent, the daemon dereferences the resulting NULL pointer and crashes. The request requires no authentication, allowing any local user to crash the gssproxy daemon via its Unix socket. The daemon does not automatically restart, resulting in a persistent denial of service that also affects dependent services such as Kerberized NFS and IdM.","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-2026-116497","source_modified_at":"2026-10-26T17:57:34.509Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116497","source_modified_at":"2026-10-26T17:57:34.509Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116497","source_modified_at":"2026-10-26T17:57:34.509Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116497","source_modified_at":"2026-10-26T17:57:34.509Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116497","source_modified_at":"2026-10-26T17:57:34.509Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Red Hat OpenShift Container Platform 4","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116497","source_modified_at":"2026-10-26T17:57:34.509Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"Red Hat OpenShift Container Platform 4","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":5.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T14:31:23.205Z","modified_at":"2026-10-26T17:57:34.509Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116497","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T17:57:34.509Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-116497","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2560642","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":"2026-10-26T17:48:31.350632Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-26T17:57:34.509Z","content_hash":"2f29c657d72f24009cb73552588ccc5b65b0b2abbd9a9f733500b57aa6917bca"}}
