Detailsinfo

A vulnerability was found in Linux Kernel up to 7.2.5. It has been rated as problematic. Affected by this issue is the function hidpp_ff_init of the component logitech-hidpp. The manipulation with an unknown input leads to a release of resource vulnerability. Using CWE to declare the problem leads to CWE-772. The product does not release a resource after its effective lifetime has ended, i.e., after the resource is no longer needed. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: HID: logitech-hidpp: Fix FF device cleanup on init failure hidpp_ff_init() creates the input force-feedback device with input_ff_create(), then allocates the HID++ FF private data, effect ID array, and workqueue. If any of those allocations fail after input_ff_create() succeeds, the function returns an error without destroying the FF device. Add an unwind path that frees the private allocations made by hidpp_ff_init() and calls input_ff_destroy() for failures after input_ff_create() succeeds.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2026-90330 since 09/11/2026. The exploitation is known to be easy. Local access is required to approach this attack.
