Since a failed\nntfs_bitmap_clear_run() rolls back its partial modifications, no\nbits were cleared for that run, yet its length still inflates\nvol->free_clusters, corrupting statfs output and the allocator's\nfree space gate.\n\nOnly count runs whose bitmap clear succeeded.","state":0,"publishedAt":"2026-09-25T10:36:15.974+00:00","modifiedAt":"2026-10-19T09:14:32.894+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                        \"fs/ntfs/lcnalloc.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"11ccc9107dc460de28af90fac1f42404d9802735\",\n                            \"lessThan\": \"7eb97d8828e7758b9c81277f7802e740a800f78a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"11ccc9107dc460de28af90fac1f42404d9802735\",\n                            \"lessThan\": \"be9e89ccb8e52a3e4b67feeb03ebd8133091dc7e\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\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                        \"fs/ntfs/lcnalloc.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.1\",\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/7eb97d8828e7758b9c81277f7802e740a800f78a","https://git.kernel.org/stable/c/be9e89ccb8e52a3e4b67feeb03ebd8133091dc7e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98139","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98139","identifiers":["CVE-2026-98139"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
