CVE-2026-68091Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: HID: wacom: stop hardware after post-start probe failures wacom_parse_and_register() starts HID hardware before registering inputs and initializing pad LEDs/remotes. Those later steps can fail, but their error paths currently release Wacom resources without stopping the HID hardware. Route post-hid_hw_start() failures through hid_hw_stop() before releasing driver resources. This issue was identified during our ongoing static-analysis research while reviewing kernel code. When the `wacom_parse_and_register()` function encounters failures after starting the Human Interface Device (HID) hardware, its error handling path releases Wacom resources without properly stopping the HID hardware. This improper resource management…
