{"id":"CVE-2026-90122","summary":"clk: visconti: Make sure clk_init_data is fully initialized","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nclk: visconti: 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\nvisconti_clk_register_gate() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter in uninitialized, and\nthus 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":"2026-09-19T03:47:28.687842173Z","published":"2026-09-17T16:06:25.910Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90122.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e97c22b286e1918c6f48bad7e77fb8240a24b4a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1cc0539e5b0906bace15d3fc7347b344a017cc02"},{"type":"WEB","url":"https://git.kernel.org/stable/c/39c0e6c844a14945040cca4ccf6997792ab764c4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ecfa72e74c6e2a765fa5bc1da574e5beae588f2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8f7980033e9f7ecaaecd873a0b5bf6b6c87d7e5a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f756f1965bad65e6066608f33c36988cd10302a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90122.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90122"},{"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":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa"},{"fixed":"0e97c22b286e1918c6f48bad7e77fb8240a24b4a"},{"fixed":"9f756f1965bad65e6066608f33c36988cd10302a"},{"fixed":"1cc0539e5b0906bace15d3fc7347b344a017cc02"},{"fixed":"8f7980033e9f7ecaaecd873a0b5bf6b6c87d7e5a"},{"fixed":"5ecfa72e74c6e2a765fa5bc1da574e5beae588f2"},{"fixed":"39c0e6c844a14945040cca4ccf6997792ab764c4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90122.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.17.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90122.json"}}],"schema_version":"1.9.0"}
