8.8 HIGH

Published 2026-09-16 · Updated 2026-09-21

AI risk analysis

Summary: The flaw allows an attacker to exploit a race condition in the Linux kernel's HID input registration, leading to potential memory corruption and execution of arbitrary code.
Exploitability: Exploitation requires a race condition between the input device registration and the probe failure handling, making it moderately difficult. Precondition is the presence of a vulnerable HID device driver.
Blast radius: If exploited, the flaw could lead to privilege escalation or system compromise, impacting the entire system.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to the specific version 5.19.2 or later, as published in the advisory.

NVD description

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.
