Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> HID: wacom: stop hardware after post-start probe failures<br /> <br /> wacom_parse_and_register() starts HID hardware before registering inputs<br /> and initializing pad LEDs/remotes. Those later steps can fail, but their<br /> error paths currently release Wacom resources without stopping the HID<br /> hardware.<br /> <br /> Route post-hid_hw_start() failures through hid_hw_stop() before<br /> releasing driver resources.<br /> <br /> This issue was identified during our ongoing static-analysis research while<br /> reviewing kernel code.
