This caused\na double free issue.\n\nTo resolve this, reordered `kmalloc()` and `usb_alloc_urb()` calls to\nsimplify the initialization sequence and removed the redundant\n`kfree(buf)`.  Now, `buf` is allocated after `usb_alloc_urb()`, ensuring\nit is correctly managed by  `usb_fill_int_urb()` and freed by\n`usb_free_urb()` as intended.","published":"2024-12-27T14:15:29.000Z","lastModified":"2026-06-17T08:08:36.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-415"],"affected":["linux/linux kernel"],"epss":{"score":0.00233,"percentile":0.14114,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%).
