CVE-2026-90041

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

HID: sony: clean up device list on probe failure

sony_input_configured() adds some controllers to sony_device_list before HID core registers their input devices. input_register_device() can fail after the callback returns successfully. sony_probe() then observes that HID_CLAIMED_INPUT is clear and unwinds, but only stops the HID hardware. The devres-managed sony_sc is freed while its list node remains linked, so the next matching controller traverses freed memory.

Initialize the list node and device ID to inactive states. Make list removal idempotent and run the driver-private cleanup on every probe failure path. This also makes a second cleanup safe when sony_input_configured() already unwound a partial initialization before sony_probe() handles the missing input claim.

Found by 0sec (https://0sec.ai) using automated source analysis; verified against the HID input registration and probe unwind paths.
