{"schema":"threatline.record/2","record":{"id":"CVE-2026-99114","aliases":[],"summary":"ksmbd: initialize FileSystemControlFlags in FS_CONTROL_INFORMATION","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: initialize FileSystemControlFlags in FS_CONTROL_INFORMATION\n\nsmb2_get_info_filesystem() reports 48 bytes for FS_CONTROL_INFORMATION,\nthat is the whole of struct smb2_fs_control_info, but never assigns\nFileSystemControlFlags.  Those four bytes go to the client as they are\nfound in the response buffer.\n\nThe buffer is zeroed on allocation, so a standalone request leaks\nnothing.  A compound request can leak: the offset of the next response\nis advanced by the length pinned for the previous one, so a reply that\nwas written into the buffer and then dropped in favour of the short\nerror response of smb2_set_err_rsp() stays there, and the next reply is\nlaid over it with only the header cleared.\n\nksmbd does not implement quota tracking, so report no control flags.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99114","source_modified_at":"2026-10-28T10:34:31.576Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"e2f34481b24db2fd634b5edb0a5bd0e4d38cc6e9","lessThan":"d8c450ad0d08980b39b08d435efa921086c8b227","status":"affected","versionType":"git"},{"version":"e2f34481b24db2fd634b5edb0a5bd0e4d38cc6e9","lessThan":"03bb4338c3a7c3fc4decf699a35753f0891aab2a","status":"affected","versionType":"git"},{"version":"e2f34481b24db2fd634b5edb0a5bd0e4d38cc6e9","lessThan":"c0cd3fc6824122014da2b3b0cb7ddeaa2946ec8e","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99114","source_modified_at":"2026-10-28T10:34:31.576Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.15","status":"affected"},{"version":"0","lessThan":"5.15","status":"unaffected","versionType":"semver"},{"version":"6.18.59","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.13","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99114","source_modified_at":"2026-10-28T10:34:31.576Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"03bb4338c3a7c3fc4decf699a35753f0891aab2a","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T10:34:31.576Z","modified_at":"2026-10-28T10:34:31.576Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99114","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:34:31.576Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/d8c450ad0d08980b39b08d435efa921086c8b227"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/03bb4338c3a7c3fc4decf699a35753f0891aab2a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c0cd3fc6824122014da2b3b0cb7ddeaa2946ec8e"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-28T10:34:31.576Z","content_hash":"10a4a7fbc0512a3e7934eb45a0459f5e86ef32a59f14411722a2c0dc0bab69c9"}}
