{"cve":"CVE-2026-72005","nvd":{"published":"2026-08-15T06:20:59.113","modified":"2026-10-19T22:17:21.383","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rt2x00: avoid full teardown before work setup in probe\n\nrt2x00lib_probe_dev() uses the full rt2x00lib_remove_dev() teardown for\nall probe failures. However, drv_data allocation and workqueue allocation\ncan fail before intf_work, autowakeup_work and sleep_work have been\ninitialized.\n\nDo not enter the full remove path until the probe has reached the point\nwhere those work items are set up. Return directly for drv_data allocation\nfailure, and use a small early cleanup path for workqueue allocation\nfailure.\n\nThis issue was found by our static analysis tool and then confirmed by\nmanual review of rt2x00lib_probe_dev() and rt2x00lib_remove_dev(). The\nearly probe exits should not call a common teardown path that assumes the\nlater work setup has already completed.\n\nA QEMU PoC forced alloc_ordered_workqueue() to fail before the work\ninitializers are reached. The resulting fail path entered\nrt2x00lib_remove_dev(), and DEBUG_OBJECTS reported invalid work drains with\nrt2x00lib_probe_dev() and rt2x00lib_remove_dev() in the stack.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-404"],"references":["https://git.kernel.org/stable/c/3c0427d719bddb33caf18ff4ffb77cb47de7eb00","https://git.kernel.org/stable/c/536fb3d739d75a03cb318c0c6fe799425cfea501","https://git.kernel.org/stable/c/56994852d704535ea354a4627ca667b1b4fa0deb","https://git.kernel.org/stable/c/59afe6148927395cf86f9429900e029a48b1d42b","https://git.kernel.org/stable/c/66bd9b1a72de7c2f5141b02d796048aafaed8a49"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-72005","score":0.00164,"percentile":0.05609,"date":"2026-10-25"},"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).
