CVE-2026-89623

A flaw was found in the Linux kernel's HID (Human Interface Device) mcp2221 driver. This vulnerability occurs when the device's input/output (IO) operations are not properly stopped before hardware teardown during device removal or probe failure. This timing issue can lead to a use-after-free condition, where the system attempts to access memory that has already been released. Such a condition could result in system instability or a denial of service.
