{"id":"AZL-88484","summary":"CVE-2026-46092 affecting package kernel for versions less than 6.6.139.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: check for PCI upstream bridge existence\n\npci_upstream_bridge() returns NULL if the device is on a root bus.  If\n8821CE is installed in the system with such a PCI topology, the probing\nroutine will crash.  This has probably been unnoticed as 8821CE is mostly\nsupplied in laptops where there is a PCI-to-PCI bridge located upstream\nfrom the device.  However the card might be installed on a system with\ndifferent configuration.\n\nCheck if the bridge does exist for the specific workaround to be applied.\n\nFound by Linux Verification Center (linuxtesting.org) with Svace static\nanalysis tool.","modified":"2026-08-30T05:26:50Z","published":"2026-05-27T14:17:30Z","upstream":["CVE-2026-46092"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46092"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.139.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88484.json"}}],"schema_version":"1.9.0"}
