{"id":"AZL-88905","summary":"CVE-2026-46187 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rsi: fix kthread lifetime race between self-exit and external-stop\n\nRSI driver use both self-exit(kthread_complete_and_exit) and external-stop\n(kthread_stop) when killing a kthread. Generally, kthread_stop() is called\nfirst, and in this case, no particular issues occur.\n\nHowever, in rare instances where kthread_complete_and_exit() is called\nfirst and then kthread_stop() is called, a UAF occurs because the kthread\nobject, which has already exited and been freed, is accessed again.\n\nTherefore, to prevent this with minimal modification, you must remove\nkthread_stop() and change the code to wait until the self-exit operation\nis completed.","modified":"2026-08-28T17:48:09.961893034Z","published":"2026-05-28T10:16:34Z","upstream":["CVE-2026-46187"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46187"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88905.json"}}],"schema_version":"1.9.0"}
