{"id":"AZL-94913","summary":"CVE-2026-68152 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\namt: fix use-after-free in AMT delayed works\n\nWhen an AMT device is removed, pending delayed works can still access\nthe freed amt_dev structure, which may result in kernel crashes or\nmemory corruption.\n\namt_dev_stop() cancels req_wq and discovery_wq with\ncancel_delayed_work_sync(), but these works can be scheduled again\nfrom event_wq after the cancellation. This allows delayed works to\naccess the freed amt_dev structure after the netdev has been released.\n\nThe following is a simple race scenario:\n\nCPU0                         CPU1\n\namt_dev_stop()\ncancel_delayed_work_sync()\n                             amt_event_work()\n                             mod_delayed_work(req_wq)\nfree netdev\n                             req_wq accesses freed amt_dev\n\nUse disable_delayed_work_sync() in amt_dev_stop() to prevent req_wq and\ndiscovery_wq from being queued again and wait for running work items\nto complete.\n\nThe delayed works are disabled after initialization in\namt_newlink() and enabled only when the device is successfully opened.\nThis keeps the delayed work lifecycle synchronized with the lifetime\nof the AMT device.","modified":"2026-08-30T05:26:50Z","published":"2026-08-10T13:20:01Z","upstream":["CVE-2026-68152"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68152"}],"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-94913.json"}}],"schema_version":"1.9.0"}
