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\nadf4377_clk_register() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter is uninitialized, and\nthus may cause a crash.\n\nSimilarly, adf4377_clk_register() fills in only parent_data.fw_name,\nleaving other members of the clk_parent_data structure uninitialized.\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":"2026-10-18T15:44:51.64+00:00","modifiedAt":"2026-10-19T09:23:35.252+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/iio/frequency/adf4377.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"60e5448ddbec2dc206027a4850604d8fdf9973b7\",\n                            \"lessThan\": \"6564f394a4a95fad534643a6ca0f1d36ff081799\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"60e5448ddbec2dc206027a4850604d8fdf9973b7\",\n                            \"lessThan\": \"e787fd23d5063c61582c3c27522240b6e6703fde\",\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/iio/frequency/adf4377.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.10\",\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/6564f394a4a95fad534643a6ca0f1d36ff081799","https://git.kernel.org/stable/c/e787fd23d5063c61582c3c27522240b6e6703fde"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98667","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98667","identifiers":["CVE-2026-98667"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
