Make list\nremoval idempotent and run the driver-private cleanup on every probe\nfailure path. This also makes a second cleanup safe when\nsony_input_configured() already unwound a partial initialization before\nsony_probe() handles the missing input claim.\n\nFound by 0sec (https://0sec.ai) using automated source analysis;\nverified against the HID input registration and probe unwind paths.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3b4709e4864908bb06c48c500cc8db8d3d55d139","tags":[]},{"url":"https://git.kernel.org/stable/c/7c65699a3a311198a07659a614fe64d45924839e","tags":[]},{"url":"https://git.kernel.org/stable/c/b84544ef00a27e8081498d33af7dac33b6cb8418","tags":[]},{"url":"https://git.kernel.org/stable/c/d044d796e2a369c6051c7e83dce88c7baa2494d4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw allows an attacker to exploit a race condition in the Linux kernel's HID input registration, leading to potential memory corruption and execution of arbitrary code.","exploitability":"Exploitation requires a race condition between the input device registration and the probe failure handling, making it moderately difficult.
