{"id":"CVE-2026-93249","summary":"spi: amlogic-spisg: Make sure clk_init_data is fully initialized","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nspi: amlogic-spisg: 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\naml_spisg_clk_init() 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":"2026-09-25T03:48:54.353544768Z","published":"2026-09-24T15:51:14.111Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93249.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/5969a3df8361a0e20379a308c2313d3e263123de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b2702908ee23ef31bfcf241a2e07ace0eb76bd71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bfce0f324efaa605e606cbb3f0bdb8fe5c910c11"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93249.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93249"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cef9991e04aed3305c61c392e880f6e01a0c2ea4"},{"fixed":"bfce0f324efaa605e606cbb3f0bdb8fe5c910c11"},{"fixed":"5969a3df8361a0e20379a308c2313d3e263123de"},{"fixed":"b2702908ee23ef31bfcf241a2e07ace0eb76bd71"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93249.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"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-2026-93249.json"}}],"schema_version":"1.9.0"}
