{"id":"AZL-68849","summary":"CVE-2025-40030 affecting package kernel for versions less than 6.6.112.1-2","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: check the return value of pinmux_ops::get_function_name()\n\nWhile the API contract in docs doesn't specify it explicitly, the\ngeneric implementation of the get_function_name() callback from struct\npinmux_ops - pinmux_generic_get_function_name() - can fail and return\nNULL. This is already checked in pinmux_check_ops() so add a similar\ncheck in pinmux_func_name_to_selector() instead of passing the returned\npointer right down to strcmp() where the NULL can get dereferenced. This\nis normal operation when adding new pinfunctions.","modified":"2026-04-01T05:21:30.119684Z","published":"2025-10-28T12:15:36Z","upstream":["CVE-2025-40030"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-40030"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.112.1-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-68849.json"}}],"schema_version":"1.7.5"}
