{"schema":"threatline.record/2","record":{"id":"CVE-2026-97983","aliases":[],"summary":"vduse: return compat ioctl results directly","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nvduse: return compat ioctl results directly\n\nThe compat handler handles VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO, but\nthen calls the native handler. Their different command sizes make native\ndispatch return -ENOIOCTLCMD.\n\nFor GET_FD, this overwrites receive_fd()'s return value after the\ndescriptor is installed, leaking one fd per call. Return handled compat\nresults directly and use native dispatch only for other commands.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97983","source_modified_at":"2026-10-19T09:11:50.328Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"455a2a1af92651764e9eb42cec0d95ac142afc28","lessThan":"135ac58097fa5fc707bf392c5cececf59e4080c0","status":"affected","versionType":"git"},{"version":"455a2a1af92651764e9eb42cec0d95ac142afc28","lessThan":"48a4ee65e677559776349128e6a81a6041986c99","status":"affected","versionType":"git"},{"version":"7dd28904c42ee3b0728c0692dd3332c2c83e8f33","status":"affected","versionType":"git"},{"version":"7.1.5","lessThan":"7.2","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97983","source_modified_at":"2026-10-19T09:11:50.328Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"7.2","status":"affected"},{"version":"0","lessThan":"7.2","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97983","source_modified_at":"2026-10-19T09:11:50.328Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"135ac58097fa5fc707bf392c5cececf59e4080c0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97983","source_modified_at":"2026-10-19T09:11:50.328Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"48a4ee65e677559776349128e6a81a6041986c99","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97983","source_modified_at":"2026-10-19T09:11:50.328Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"7.2","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00155,"percentile":0.04321,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:23:18.940Z","modified_at":"2026-10-19T09:11:50.328Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97983","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:11:50.328Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97983","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/135ac58097fa5fc707bf392c5cececf59e4080c0"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/48a4ee65e677559776349128e6a81a6041986c99"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:11:50.328Z","content_hash":"6140d2d6983657aa9ecbba42909956f7cd3ae55ab644aacb3a81770571bfce8f"}}
