CVE-2026-90329
8.8 HIGHPublished 2026-09-17 · Updated 2026-09-18
AI risk analysis
- Summary
- This vulnerability allows concurrent report processing with probe operations, leading to potential use-after-free conditions when probe fails, impacting input handling in the Linux kernel.
- Exploitability
- Exploitation requires concurrent report processing and probe failure, making it moderately difficult. Precondition is the presence of concurrent report callbacks during probe failure.
- Blast radius
- If exploited, it could lead to denial of service or privilege escalation through use-after-free conditions.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to the Linux kernel version 6.1.17 or later.

NVD description
In the Linux kernel, the following vulnerability has been resolved: HID: synchronize input before cleaning up a failed probe hid_device_io_start() allows reports to run concurrently with probe. If the probe subsequently fails, __hid_device_probe() releases driver resources and clears hdev->driver without first excluding those report callbacks. For example, a report may enter hidraw_report_event() while the failure path frees the associated hidraw object, leading to a use-after-free when the report takes the object's list lock. Stop input before performing failed-probe cleanup. This reacquires driver_input_lock and waits for any report callback already in progress.
