CVE-2026-98501
In the Linux kernel, the following vulnerability has been resolved: HID: alps: fix use-after-free on input2 registration failure alps_input_configured() store
In the Linux kernel, the following vulnerability has been resolved:
HID: alps: fix use-after-free on input2 registration failure
alps_input_configured() stores data->input2 before calling
input_register_device(). If registration fails, input_free_device()
frees the input device but data->input2 still points to the freed memory.
alps_input_configured() calls hid_hw_open() before allocating input2, so
URBs are already active and raw_event can fire during the failure window.
A U1_SP_ABSOLUTE_REPORT_ID report arriving then causes u1_raw_event()
to dereference the freed data->input2 -> use-after-free.
Fix by only storing input2 into drvdata after successful registration
and adding a NULL guard in the raw_event path.
