{"apiVersion":"1.0","identifier":"CVE-2026-72005","description":"In the Linux kernel, the following vulnerability has been resolved: wifi: rt2x00: avoid full teardown before work setup in probe rt2x00lib_probe_dev() uses the full rt2x00lib_remove_dev() teardown for all probe failures. However, drv_data allocation and workqueue allocation can fail before intf_work, autowakeup_work and sleep_work have been initialized. Do not enter the full remove path until the probe has reached the point where those work items are set up. Return directly for drv_data allocation failure, and use a small early cleanup path for workqueue allocation failure. This issue was found by our static analysis tool and then confirmed by manual review of rt2x00lib_probe_dev() and rt2x00lib_remove_dev(). The early probe exits should not call a common teardown path that assumes the later work setup has already completed. A QEMU PoC forced alloc_ordered_workqueue() to fail before the work initializers are reached. The resulting fail path entered rt2x00lib_remove_dev(), and DEBUG_OBJECTS reported invalid work drains with rt2x00lib_probe_dev() and rt2x00lib_remove_dev() in the stack.","publishedAt":"2026-08-15T06:20:59","lastModifiedAt":"2026-08-17T06:17:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72005","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00164,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72005","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72005","en":"https://www.redsauce.net/en/cves/CVE-2026-72005","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72005","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72005","de":"https://www.redsauce.net/de/cves/CVE-2026-72005","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72005","el":"https://www.redsauce.net/el/cves/CVE-2026-72005"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72005"}}
