{"id":"CVE-2026-74369","summary":"liveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nliveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish()\n\nIn luo_file_unpreserve_files() and luo_file_finish(), reorder\nmodule_put() and xa_erase() to ensure the file handler module remains\npinned while its operations are being accessed.\n\nSpecifically, luo_get_id() dereferences fh-\u003eops-\u003eget_id, so the module\nreference must be held until after xa_erase() (which calls luo_get_id)\ncompletes.\n\nFor luo_file_finish(), this requires moving the module_put() call out of\nthe luo_file_finish_one() helper and into the main loop of\nluo_file_finish() itself.","modified":"2026-08-18T03:30:56.096131853Z","published":"2026-08-15T05:58:50.280Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74369.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/291dcd37c8c8f8f8e1bccc92228f44bf371762a8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7fca3db635022429382cf26e5b08b33558e375d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74369.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74369"},{"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":"00d0b372374f2528394aabf7b1f53f8dafe294de"},{"fixed":"f7fca3db635022429382cf26e5b08b33558e375d"},{"fixed":"291dcd37c8c8f8f8e1bccc92228f44bf371762a8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74369.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74369.json"}}],"schema_version":"1.9.0"}
