{"id":"CVE-2025-71311","summary":"fs/ntfs3: Initialize new folios before use","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: Initialize new folios before use\n\nKMSAN reports an uninitialized value in longest_match_std(), invoked\nfrom ntfs_compress_write(). When new folios are allocated without being\nmarked uptodate and ni_read_frame() is skipped because the caller expects\nthe frame to be completely overwritten, some reserved folios may remain\nonly partially filled, leaving the rest memory uninitialized.","modified":"2026-07-15T01:48:59.671799834Z","published":"2026-05-27T12:24:02.532Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71311.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/41d79f8e2a36622d148719bf7c18b46ac1264284"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5a30cc03bde169ad558695b26da6ea7e55f6194a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd6c81527d097b3b0bf5a15c2fdc9657d045144c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f223ebffa185cc8da934333c5a31ff2d4f992dc9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71311.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71311"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"584f60ba22f79c89e6708ab82a5b5d9b8fa21fb2"},{"fixed":"dd6c81527d097b3b0bf5a15c2fdc9657d045144c"},{"fixed":"5a30cc03bde169ad558695b26da6ea7e55f6194a"},{"fixed":"41d79f8e2a36622d148719bf7c18b46ac1264284"},{"fixed":"f223ebffa185cc8da934333c5a31ff2d4f992dc9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71311.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71311.json"}}],"schema_version":"1.7.5"}
