Linux Kernel up to 7.2.0 HID nintendo_hid_probe use after free

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 7.2.0 and classified as very critical. Affected by this issue is the function nintendo_hid_probe of the component HID. The manipulation with an unknown input leads to a use after free vulnerability. Using CWE to declare the problem leads to CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: HID: nintendo: stop device IO before hid_hw_stop on probe failure nintendo_hid_probe() calls hid_device_io_start() before joycon_init() and joycon_leds_create(). If either fails, the error path jumps to err_close which calls hid_hw_close()/hid_hw_stop() without first calling hid_device_io_stop(). hid_hw_stop() does not stop device IO, so hid_input_report() may still run and access driver data that is being torn down, resulting in a use-after-free. Add an err_io_stop label that calls hid_device_io_stop() before hid_hw_close(), and point the two post-io_start error paths at it.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2026-80770 since 08/26/2026. The exploitation is known to be easy. The attack may be launched remotely. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 09/04/2026).

Upgrading to version 6.1.187, 6.6.156, 6.12.106, 6.18.47, 7.1.11, 7.2.1 or 7.3-rc1 eliminates this vulnerability. Applying the patch c2f3d51c7f5222f5b51e0c90f02258d82e1b44dd/c023443f0e6cfd257846b6515c93c1ea08026593/03a84f9f88b42cd49752ec0259922b67e4b88598/5efcd7bbfaaec67d137c99aa0940fa34375db27f/13a3edf96568a0b7aacadea07c2adec53ac8f630/2e0d98dc8a6dea5fc2b72bf66e0dcbd5488644b4/1f74d3bff6fe04a64e02ab3661d2e0d554565aa6 is able to eliminate this problem.
