{"id":"CVE-2026-89837","summary":"f2fs: fix dentry folio leak in find_in_level","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix dentry folio leak in find_in_level\n\nfind_in_level() gets a dentry folio with f2fs_find_data_folio() before\ncalling find_in_block().  If find_in_block() returns an error, the\nfunction stores the error in res_folio and breaks out of the loop without\ndropping the dentry folio.\n\nThis leaks the folio reference on the find_in_block() error path.  Drop\nthe dentry folio before returning the error to the caller.","modified":"2026-09-18T03:48:33.465593190Z","published":"2026-09-16T10:31:11.557Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89837.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/93a3e6a4c9e726a13a935963e8dc43d181db1527"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aefb4b0f465b6f95fe02b52d1822a3fb4a9ae922"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cca7d3e30bf30333314e31bc70b9a739f1342167"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89837.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89837"},{"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":"7ad08a58bf67594057362e45cbddd3e27e53e557"},{"fixed":"aefb4b0f465b6f95fe02b52d1822a3fb4a9ae922"},{"fixed":"93a3e6a4c9e726a13a935963e8dc43d181db1527"},{"fixed":"cca7d3e30bf30333314e31bc70b9a739f1342167"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89837.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89837.json"}}],"schema_version":"1.9.0"}
