CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's USB subsystem, specifically in the handling of wakeup notifications, where a race condition could lead to dereferencing freed memory. This flaw can be exploited by the xHCI driver during interrupt handling, potentially resulting in system instability or crashes. Linux system administrators and developers working with USB devices should prioritize addressing this issue to ensure system reliability and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: usb: core: Add lock to usb_wakeup_notification() Add a spin lock to usb_wakeup notification to prevent a race condition with dereferencing freed memory. This could be hit by the xHCI driver as it calls this function from an IRQ and could race with the hub_disconnect() function, which properly grabs this lock to protect the state of the device.
