Description OSIDB Bzimport 2026-08-10 12:02:25 UTC
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.
