Detailsinfo

A vulnerability, which was classified as very critical, was found in Linux Kernel up to 6.12.110/6.18.52/7.2.6/7.3-rc2. This affects the function ccp_probe of the component hwmon. The manipulation with an unknown input leads to a use after free vulnerability. CWE is classifying the issue as CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: hwmon: (corsair-cpro) Remove debugfs entries when probe fails ccp_debugfs_init() registers debugfs files whose private data is the devm allocated ccp. If hwmon_device_register_with_info() fails right after it, ccp_probe() returns without removing them: the HID core then frees ccp, and ccp_remove() is not called for a failed probe, so the files stay behind. Reading one of them dereferences the freed pointer. Remove the debugfs entries on that error path. debugfs_remove_recursive() waits for readers already inside the show callbacks, so ccp is no longer reachable through debugfs by the time probe returns.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-97967 since 09/25/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Additional levels of successful authentication are necessary for exploitation. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 09/25/2026).

Upgrading to version 6.12.111, 6.18.53, 7.2.7 or 7.3-rc3 eliminates this vulnerability. Applying the patch ae01aafd8214e48cb7eff11e92dfbf3778d52d9d/a5de53b08cc319dadce6fb68d33749ea37962952/fdc1bc23ff59ee308042342cefcb918d6efba409/4ee875c423c66c45d7ef7bbff403cd0e3971e0a2 is able to eliminate this problem.
