{"id":"AZL-69030","summary":"CVE-2025-40085 affecting package kernel for versions less than 6.6.117.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Fix NULL pointer deference in try_to_register_card\n\nIn try_to_register_card(), the return value of usb_ifnum_to_if() is\npassed directly to usb_interface_claimed() without a NULL check, which\nwill lead to a NULL pointer dereference when creating an invalid\nUSB audio device. Fix this by adding a check to ensure the interface\npointer is valid before passing it to usb_interface_claimed().","modified":"2026-04-01T05:21:31.944375Z","published":"2025-10-29T14:15:55Z","upstream":["CVE-2025-40085"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-40085"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.117.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-69030.json"}}],"schema_version":"1.7.5"}
