{"id":"AZL-102447","summary":"CVE-2026-90122 affecting package kernel 6.6.150.1-1","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":"2026-09-19T05:33:49Z","published":"2026-09-17T17:17:04Z","upstream":["CVE-2026-90122"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90122"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102447.json"}}],"schema_version":"1.9.0"}
