{"id":"CVE-2026-98667","summary":"iio: frequency: adf4377: Fully initialize clk_init_data and clk_parent_data","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: frequency: adf4377: Fully initialize clk_init_data and clk_parent_data\n\nThe clk_init_data structure contains several mutually-exclusive members\nfor different methods to specify the possible parents of a clock,\nprompting drivers to initialize only the members they need.  However,\nnot initializing all members may cause subtle issues, which are only\nexposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is\nenabled.\n\nadf4377_clk_register() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter is uninitialized, and\nthus may cause a crash.\n\nSimilarly, adf4377_clk_register() fills in only parent_data.fw_name,\nleaving other members of the clk_parent_data structure uninitialized.\n\nMake sure all members are fully initialized, to fix such bugs, and to\navoid future breakage when converting drivers to a different method for\nspecifying the parents.","modified":"2026-10-20T02:30:45.659368693Z","published":"2026-10-18T15:44:51.640Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98667.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6564f394a4a95fad534643a6ca0f1d36ff081799"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e787fd23d5063c61582c3c27522240b6e6703fde"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98667.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98667"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"60e5448ddbec2dc206027a4850604d8fdf9973b7"},{"fixed":"6564f394a4a95fad534643a6ca0f1d36ff081799"},{"fixed":"e787fd23d5063c61582c3c27522240b6e6703fde"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98667.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98667.json"}}],"schema_version":"1.9.0"}
