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.","state":0,"publishedAt":"2026-09-24T15:51:14.111+00:00","modifiedAt":"2026-10-19T09:08:02.994+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/spi/spi-amlogic-spisg.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"cef9991e04aed3305c61c392e880f6e01a0c2ea4\",\n                            \"lessThan\": \"bfce0f324efaa605e606cbb3f0bdb8fe5c910c11\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"cef9991e04aed3305c61c392e880f6e01a0c2ea4\",\n                            \"lessThan\": \"5969a3df8361a0e20379a308c2313d3e263123de\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"cef9991e04aed3305c61c392e880f6e01a0c2ea4\",\n                            \"lessThan\": \"b2702908ee23ef31bfcf241a2e07ace0eb76bd71\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/spi/spi-amlogic-spisg.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.17\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.17\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.52\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/bfce0f324efaa605e606cbb3f0bdb8fe5c910c11","https://git.kernel.org/stable/c/5969a3df8361a0e20379a308c2313d3e263123de","https://git.kernel.org/stable/c/b2702908ee23ef31bfcf241a2e07ace0eb76bd71"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93249","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93249","identifiers":["CVE-2026-93249"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
