Serialize those operations and the resident\nconversion with the runlist lock.\n\nntfs_attr_map_cluster() can merge a newly allocated run before updating\nmapping pairs. If the update fails, free the clusters and restore both\nthe in-memory runlist and on-disk mapping pairs from a saved runlist.\nMark the volume in error if either rollback step fails.","state":0,"publishedAt":"2026-10-06T08:46:10.751+00:00","modifiedAt":"2026-10-19T09:17:25.955+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/attrib.c\",\n                        \"fs/ntfs/attrib.h\",\n                        \"fs/ntfs/attrlist.c\",\n                        \"fs/ntfs/attrlist.h\",\n                        \"fs/ntfs/compress.c\",\n                        \"fs/ntfs/file.c\",\n                        \"fs/ntfs/inode.c\",\n                        \"fs/ntfs/mft.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"495e90fa334828d4119061e2726af51d0a0fb4ed\",\n                            \"lessThan\": \"742797432e8c9b0dd54ecc523c185e26b09d79a0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"495e90fa334828d4119061e2726af51d0a0fb4ed\",\n                            \"lessThan\": \"91709ba5d6d709b2b663287b7e871e2c6b480502\",\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/attrib.c\",\n                        \"fs/ntfs/attrib.h\",\n                        \"fs/ntfs/attrlist.c\",\n                        \"fs/ntfs/attrlist.h\",\n                        \"fs/ntfs/compress.c\",\n                        \"fs/ntfs/file.c\",\n                        \"fs/ntfs/inode.c\",\n                        \"fs/ntfs/mft.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\": \"7.2.8\",\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":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/742797432e8c9b0dd54ecc523c185e26b09d79a0","https://git.kernel.org/stable/c/91709ba5d6d709b2b663287b7e871e2c6b480502"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98315","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98315","identifiers":["CVE-2026-98315"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
