{"id":"CVE-2026-68461","summary":"device property: initialize the remaining fields of fwnode_handle in fwnode_init()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndevice property: initialize the remaining fields of fwnode_handle in fwnode_init()\n\nIf a firmware node is allocated on the stack (for instance: temporary\nsoftware node whose life-time we control) or on the heap - but using a\nnon-zeroing allocation function - and initialized using fwnode_init(),\nits secondary pointer will contain uninitialized memory which likely\nwill be neither NULL nor IS_ERR() and so may end up being dereferenced\n(for example: in dev_to_swnode()). Set fwnode-\u003esecondary to NULL on\ninitialization. While at it: initialize the remaining fields of struct\nfwnode_handle too just to be sure.\n\n[ Fix typo in commit message. - Danilo ]","modified":"2026-08-16T03:48:26.181649769Z","published":"2026-08-15T05:51:21.219Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68461.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0198d579948322cda5178b9672d448375a32f947"},{"type":"WEB","url":"https://git.kernel.org/stable/c/173b61c9276c7b3a5fbcc63ae7aafc897fee1e18"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7eba000621fff223dd7bab484d48918c7c77a307"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c86a1f930bb2ddb85f867b4736716e82a4a4683"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c81e2af41de6a159837c7129a4fc444ac6e48046"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8542b68ba6ef4f61072098893a3f5b71c569b6c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f0b4e1cc8ad76baf49d898727eb52e91a4ef0544"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68461.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68461"},{"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":"01bb86b380a306bd937c96da36f66429f3362137"},{"fixed":"0198d579948322cda5178b9672d448375a32f947"},{"fixed":"173b61c9276c7b3a5fbcc63ae7aafc897fee1e18"},{"fixed":"f0b4e1cc8ad76baf49d898727eb52e91a4ef0544"},{"fixed":"c8542b68ba6ef4f61072098893a3f5b71c569b6c"},{"fixed":"9c86a1f930bb2ddb85f867b4736716e82a4a4683"},{"fixed":"c81e2af41de6a159837c7129a4fc444ac6e48046"},{"fixed":"7eba000621fff223dd7bab484d48918c7c77a307"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68461.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68461.json"}}],"schema_version":"1.9.0"}
