{"id":"AZL-100617","summary":"CVE-2026-89464 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: twl4030_charger: cancel workers via devm\n\nbci is devm-allocated. Two workers (bci-\u003ework and bci-\u003ecurrent_worker)\ndereference it. twl4030_bci_remove() disables charging and masks\ninterrupts. It cancels neither worker. A worker pending at remove() can\nrun after devm frees bci.\n\nThe USB transceiver comes from devm_usb_get_phy_by_node(). devm\nunregisters its notifier only after remove() returns. A cancel_work_sync()\nin remove() can then race a notifier reschedule. devm_work_autocancel()\nand devm_delayed_work_autocancel() avoid that. They cancel the workers\nduring devm release, before bci is freed.\n\nThe current_worker is registered first, since devm will cancel in\nreverse order and bci-\u003ework can reschedule current_worker.\n\n[Move comment about order into the commit message]","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:27Z","upstream":["CVE-2026-89464"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89464"}],"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-100617.json"}}],"schema_version":"1.9.0"}
