{"id":"AZL-105978","summary":"CVE-2026-98194 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libertas_tf: fix UAF in lbtf_free_adapter()\n\nlbtf_free_adapter() calls lbtf_free_cmd_buffer() to free the command\nbuffers before calling timer_delete_sync() to wait for the command\ntimer callback.  If the timer callback (command_timer_fn) is already\nrunning when lbtf_free_cmd_buffer() frees the command array, the\ncallback dereferences priv-\u003ecur_cmd-\u003ecmdbuf which points to freed\nmemory.\n\nSwap the order so that timer_delete_sync() runs first, ensuring any\nin-flight callback has completed before the command buffers are freed.","modified":"2026-10-08T05:35:32Z","published":"2026-10-06T09:18:04Z","upstream":["CVE-2026-98194"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98194"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105978.json"}}],"schema_version":"1.9.0"}
