{"id":"AZL-101324","summary":"CVE-2026-90019 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: fix null pointer dereference in usb_put_function_instance()\n\nusb_put_function_instance() attempts to dereference fd inside fi struct\nto get mod in uvc_alloc_inst() error path. However, fd is not allocated\nuntil later in try_get_usb_function_instance() after allocating fi in\nuvc_alloc_inst() and thus guranteed to be null in error path. Fix this\nby adding a null check for fi-\u003efd that returns if fd is null.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:17:14Z","upstream":["CVE-2026-90019"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90019"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-101324.json"}}],"schema_version":"1.9.0"}
