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.","state":0,"publishedAt":"2026-09-25T10:23:18.94+00:00","modifiedAt":"2026-10-19T09:11:50.328+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/vdpa/vdpa_user/vduse_dev.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"455a2a1af92651764e9eb42cec0d95ac142afc28\",\n                            \"lessThan\": \"135ac58097fa5fc707bf392c5cececf59e4080c0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"455a2a1af92651764e9eb42cec0d95ac142afc28\",\n                            \"lessThan\": \"48a4ee65e677559776349128e6a81a6041986c99\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"7dd28904c42ee3b0728c0692dd3332c2c83e8f33\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"7.1.5\",\n                            \"lessThan\": \"7.2\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/vdpa/vdpa_user/vduse_dev.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.7\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/135ac58097fa5fc707bf392c5cececf59e4080c0","https://git.kernel.org/stable/c/48a4ee65e677559776349128e6a81a6041986c99"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97983","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97983","identifiers":["CVE-2026-97983"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
