It also never drains in-flight netfs I/O on\nthe target.  The clone path never takes the invalidate_lock at all (only\ni_rwsem), uses a bare truncate_inode_pages_range() and likewise does not\ndrain outstanding I/O.\n\nAs a result an asynchronous destination writeback can complete after the\nserver-side copy/clone has run and reinstate stale data over the region\njust written by the server, corrupting the file.  This is the same class\nof corruption as commit d7d2adcd022b (\"smb/client: flush dirty data\nbefore punching a hole\") and has been seen randomly in generic/363\nagainst Windows Server.\n\nFix both paths to follow the established ordering: hold the target\nmapping's invalidate_lock across the flush and invalidation of the\ndestination and the server ioctl, and call netfs_wait_for_outstanding_io()\non the target to drain in-flight writes before the ioctl is issued.  Only\nthe target inode's invalidate_lock is required, as the source is merely\nflushed and not invalidated; i_rwsem (already held via\nlock_two_nondirectories()) is acquired before the invalidate_lock,\nmatching the VFS lock ordering.  Since filemap_invalidate_inode() takes\nthat same lock internally, replace it with its own unmap/flush/invalidate\nsteps instead of calling it, and return early on a zero-length copy to\navoid a range underflow.","score":null,"severity":"unknown","published":"2026-10-18T15:45:47.375Z","modified":"2026-11-10T18:15:15.197Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"c54fc3a4f375663f2361a9cbb2955fb4ef912879","status":"affected","lessThan":"6e7a06704457594f06e4ea58a17a5d162ccc735c","versionType":"git"},{"version":"c54fc3a4f375663f2361a9cbb2955fb4ef912879","status":"affected","lessThan":"e97dac26ed2cce04f9d159cc99e1eca828c5d49e","versionType":"git"},{"version":"c54fc3a4f375663f2361a9cbb2955fb4ef912879","status":"affected","lessThan":"dc71660f11ef2fecc0695a41e49cd496a9d255ab","versionType":"git"},{"version":"c54fc3a4f375663f2361a9cbb2955fb4ef912879","status":"affected","lessThan":"c9b1194e8ec99d95db25db45edd2fbf690f043ab","versionType":"git"},{"version":"358bd5f436d820bb758833050aae065b35d6986c","status":"affected","versionType":"git"},{"version":"43801359c8971cc49b4a4db5015fba77fbd09c32","status":"affected","versionType":"git"},{"version":"6.1.68","status":"affected","lessThan":"6.2","versionType":"semver"},{"version":"6.6.7","status":"affected","lessThan":"6.7","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98682"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"6.7","status":"affected"},{"version":"0","status":"unaffected","lessThan":"6.7","versionType":"semver"},{"version":"6.12.117","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.61","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98682"}],"remediation":[],"references":["https://git.kernel.org/stable/c/6e7a06704457594f06e4ea58a17a5d162ccc735c","https://git.kernel.org/stable/c/e97dac26ed2cce04f9d159cc99e1eca828c5d49e","https://git.kernel.org/stable/c/dc71660f11ef2fecc0695a41e49cd496a9d255ab","https://git.kernel.org/stable/c/c9b1194e8ec99d95db25db45edd2fbf690f043ab"],"sources":[{"name":"CVE","id":"CVE-2026-98682","modified":"2026-11-10T18:15:15.197Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98682"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-11-10T18:25:10.635Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:50:31.991Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-07T02:35:40.420Z","attemptedAt":"2026-11-07T02:35:40.420Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-07T02:35:41.237Z","attemptedAt":"2026-11-07T02:35:41.237Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-07T02:35:41.269Z","attemptedAt":"2026-11-07T02:35:41.269Z"},{"source":"EPSS","status":"available","checkedAt":"2026-11-07T02:35:39.702Z","attemptedAt":"2026-11-07T02:35:39.702Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-98682","url":"https://www.first.org/epss/","probability":0.00155,"percentile":0.047,"date":"2026-11-06","checkedAt":"2026-11-07T02:35:39.702Z"},{"source":"NVD","id":"CVE-2026-98682","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98682","modified":"2026-11-06T18:18:29.600","checkedAt":"2026-11-07T02:35:40.420Z"},{"source":"GitHub Advisory Database","id":"GHSA-78hr-gpp6-3qpr","url":"https://github.com/advisories/GHSA-78hr-gpp6-3qpr","modified":"2026-11-06T18:34:53Z","checkedAt":"2026-11-07T02:35:41.237Z"},{"source":"ENISA EUVD","id":"EUVD-2026-103936","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-103936","modified":"Nov 6, 2026, 5:15:01 PM","checkedAt":"2026-11-07T02:35:41.269Z"}],"aiSummary":null}
