{"cve":"CVE-2026-72070","nvd":{"published":"2026-08-15T06:21:16.713","modified":"2026-08-23T13:16:39.370","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libertas_tf: fix use-after-free in lbtf_free_adapter()\n\nlbtf_free_adapter() calls timer_delete(&priv->command_timer), which does\nnot wait for a running command_timer_fn() callback. lbtf_free_adapter()\nruns on the teardown path right before ieee80211_free_hw() frees priv,\nboth in lbtf_remove_card() and in the probe error path. command_timer is\narmed by mod_timer() in lbtf_cmd() whenever a firmware command is sent.\ncommand_timer_fn() dereferences priv. If a command times out as the\ndevice is removed, command_timer_fn() runs concurrently with teardown and\ndereferences priv after it has been freed.\n\nThis is the same use-after-free that commit 03cc8f90d053 (\"wifi: libertas:\nfix use-after-free in lbs_free_adapter()\") fixed in the sibling libertas\ndriver. The libertas_tf variant has the identical pattern and was left\nunchanged. Use timer_delete_sync() so any in-flight callback completes\nbefore priv is freed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/066b59e84f90d270cc15f0370166155aca507630","https://git.kernel.org/stable/c/2fba1d3b2f031a2c68e566a6d45cc5b7a8d6683d","https://git.kernel.org/stable/c/4714e95f5d61cb9c5c7c6c4e68b618f37bc6ffcf","https://git.kernel.org/stable/c/9392fd5de555272449d3d8c63410ea00f8ec853a","https://git.kernel.org/stable/c/aa6dcd5c8dd9ba1d7d0f60093bcda41c0d6d438d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72070","score":0.0022,"percentile":0.12575,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
