{"id":"CVE-2026-98001","summary":"hwmon: (ltc4282) Make sure clk_init_data is fully initialized","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (ltc4282) Make sure clk_init_data is fully initialized\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\nltc428_clk_provider_setup() does not fill in any parent clocks, and\nassumes that init.num_parents is NULL.  However, the latter in\nuninitialized, and thus may cause a crash.\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":"2026-09-26T03:48:31.560044716Z","published":"2026-09-25T10:23:29.325Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98001.json"},"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/80b46a3d066d4e2c1dd4edb90d4aa3f22ca79f39"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa08ce1ffaf36c7bdd3edd0ad65f72413639bfad"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4a96da5a3f132d80aa971ddbeb86808539ba0e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e317326d1755ea054b98e7a4833b929157461c35"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98001.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98001"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cbc29538dbf7d7400f1ffc5dd5713e6a551463a0"},{"fixed":"c4a96da5a3f132d80aa971ddbeb86808539ba0e6"},{"fixed":"80b46a3d066d4e2c1dd4edb90d4aa3f22ca79f39"},{"fixed":"aa08ce1ffaf36c7bdd3edd0ad65f72413639bfad"},{"fixed":"e317326d1755ea054b98e7a4833b929157461c35"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98001.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98001.json"}}],"schema_version":"1.9.0"}
