This crash is caused by a NULL pointer\ndereference of dev->raw pointer, even though it is checked for NULL in\nthe same function, which means there is a race condition. It occurs due\nto the incorrect order of actions in the streamzap_disconnect() function:\nrc_unregister_device() is called before usb_kill_urb(). The dev->raw\npointer is freed and set to NULL in rc_unregister_device(), and only\nafter that usb_kill_urb() waits for in-progress requests to finish.\n\nIf rc_unregister_device() is called while streamzap_callback() handler is\nnot finished, this can lead to accessing freed resources. Thus\nrc_unregister_device() should be called after usb_kill_urb().\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362","CWE-476"],"references":["https://git.kernel.org/stable/c/15483afb930fc2f883702dc96f80efbe4055235e","https://git.kernel.org/stable/c/30ef7cfee752ca318d5902cb67b60d9797ccd378","https://git.kernel.org/stable/c/4db62b60af2ccdea6ac5452fd20e29587ed85f57","https://git.kernel.org/stable/c/8760da4b9d44c36b93b6e4cf401ec7fe520015bd","https://git.kernel.org/stable/c/adf0ddb914c9e5b3e50da4c97959e82de2df75c3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-22027","score":0.00165,"percentile":0.05681,"date":"2026-11-01"},"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).
