CVE-2026-80861

CVE-2026-80861 is a vulnerability in the Linux kernel xHCI USB host controller driver (specifically the xhci-pci-renesas path). The root cause is in xhci_gen_setup(): when a USB controller (e.g., Renesas uPD720201 ) is dead or has dropped off the bus, the capability register read returns all-ones...

CVE-2026-80830 usb: core: Add lock to usb_wakeup_notification()

In the Linux kernel, the following vulnerability has been resolved: usb: core: Add lock to usbwakeupnotification Add a spin lock to usbwakeup 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...

CVE-2026-80830

This vulnerability affects the Linux kernel USB core subsystem, specifically the usb_wakeup_notification() function, which lacked a spin lock. The xHCI driver calls this function from IRQ context, creating a race condition with hub_disconnect() that can lead to dereferencing freed memory (use-aft...
