{"id":"AZL-90713","summary":"CVE-2026-53107 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libertas: don't kill URBs in interrupt context\n\nSerialization for the TX path was enforced by calling\nusb_kill_urb()/usb_kill_anchored_urbs(), to prevent transmission before\na previous URB was completed. usb_tx_block() can be called from\ninterrupt context (e.g. in the HCD giveback path), so we can't always\nuse it to kill in-flight URBs.\n\nPrevent sleeping during interrupt context by checking the tx_submitted\nanchor for existing URBs. We now return -EBUSY, to indicate there's\na pending request.","modified":"2026-08-30T05:26:50Z","published":"2026-06-24T17:17:24Z","upstream":["CVE-2026-53107"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53107"}],"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-90713.json"}}],"schema_version":"1.9.0"}
