This\nenables userland to refer to a dangling 'file' object through that still\nvalid file descriptor, leading to all kinds of use-after-free\nexploitation scenarios.\n\nFix this by deferring the call to fd_install() until after the usercopy\nhas succeeded." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Linux", "product": { "product_data": [ { "product_name": "Linux", "version": { "version_data": [ { "version_affected": "<", "version_name": "c906965dee22", "version_value": "e8d092a62449" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "4.14", "status": "affected" }, { "version": "0", "lessThan": "4.14", "status": "unaffected", "versionType": "semver" }, { "version": "4.14.264", "lessThanOrEqual": "4.14.*", "status": "unaffected", "versionType": "semver" }, { "version": "4.19.227", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.175", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.95", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.18", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.16.4", "lessThanOrEqual": "5.16.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.17", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/e8d092a62449dcfc73517ca43963d2b8f44d0516", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/e8d092a62449dcfc73517ca43963d2b8f44d0516" }, { "url": "https://git.kernel.org/stable/c/0008a0c78fc33a84e2212a7c04e6b21a36ca6f4d", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/0008a0c78fc33a84e2212a7c04e6b21a36ca6f4d" }, { "url": "https://git.kernel.org/stable/c/84b1259fe36ae0915f3d6ddcea6377779de48b82", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/84b1259fe36ae0915f3d6ddcea6377779de48b82" }, { "url": "https://git.kernel.org/stable/c/ae2b20f27732fe92055d9e7b350abc5cdf3e2414", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/ae2b20f27732fe92055d9e7b350abc5cdf3e2414" }, { "url": "https://git.kernel.org/stable/c/6066977961fc6f437bc064f628cf9b0e4571c56c", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/6066977961fc6f437bc064f628cf9b0e4571c56c" }, { "url": "https://git.kernel.org/stable/c/1d833b27fb708d6fdf5de9f6b3a8be4bd4321565", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/1d833b27fb708d6fdf5de9f6b3a8be4bd4321565" }, { "url": "https://git.kernel.org/stable/c/a0f90c8815706981c483a652a6aefca51a5e191c", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/a0f90c8815706981c483a652a6aefca51a5e191c" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
