In the Linux kernel, the following vulnerability has been resolved: net: usb: ipheth: fix carrierwork UAF on disconnect iphethsndbulkcallback re-arms the carrier-check work on any non-zero URB status: else scheduledelayedwork&dev-carrierwork, 0; Nothing ties that to the interface being up, so the...

CVE-2026-68456

A flaw was found in the Linux kernel's ueagle-atm USB driver. This driver uses an asynchronous mechanism for loading firmware but does not wait for its completion when a device is disconnected. This creates a race condition where the device's teardown can run concurrently with firmware loading. I...

CVE-2026-68456 usb: atm: ueagle-atm: wait for pre-firmware load in .disconnect()

In the Linux kernel, the following vulnerability has been resolved: usb: atm: ueagle-atm: wait for pre-firmware load in .disconnect ueagle-atm uses the asynchronous requestfirmwarenowait in .probe, but does not wait for its completion, not even in .disconnect; so, if the device is unplugged...

EUVD-2026-55332

In the Linux kernel, the following vulnerability has been resolved: media: airspy: Return queued buffers on startstreaming failure The vb2 framework hands buffers to the driver via bufqueue before calling startstreaming. If startstreaming returns an error without first returning those buffers via...

CVE-2026-64340

A flaw was found in the Linux kernel's legousbtower USB driver. This vulnerability is a use-after-free, which means the system attempts to use memory after it has been released. It occurs due to a timing issue race condition when a USB device is disconnected, potentially leading to system...

CVE-2026-64342

A flaw was found in the Linux kernel's USB iowarrior driver. This vulnerability, a use-after-free, occurs because write operations are not properly halted when a device disconnects. An attacker could potentially exploit this to cause system instability or execute arbitrary code...

CVE-2026-64334

In the Linux kernel, the following vulnerability has been resolved: USB: serial: digiacceleport: fix hard lockup on disconnect If submitting the OOB write urb fails persistently e.g if the device is being disconnected the driver would loop indefinitely with interrupts disabled. Check for urb...

Linux Distros Unpatched Vulnerability : CVE-2026-64465

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - usb: xhci: Fix sleep in atomic context in xhcifreestreams When a USB device with active stream endpoints is disconnected, xhcifreestreams is called from the...

Linux Distros Unpatched Vulnerability : CVE-2026-63821

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wifi: rtw88: usb: fix memory leaks on USB write failures When rtwusbwriteport fails to submit a USB Request Block URB e.g., due to device disconnect or ENOMEM,...

CVE-2026-63821

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: usb: fix memory leaks on USB write failures When rtwusbwriteport fails to submit a USB Request Block URB e.g., due to device disconnect or ENOMEM, the completion callback is never executed. Currently, the driver...

CVE-2026-10663

In Zephyr's experimental USB host stack CONFIGUSBHOSTSTACK, usbhdevicedisconnect subsys/usb/host/usbhdevice.c freed the root usbdevice slab object without clearing the cached pointer ctx-root. The bus removal handler devremovedhandler subsys/usb/host/usbhcore.c decides what to tear down solely fr...

CVE-2026-10663 Use-after-free / double-free of the root USB device in the experimental USB host stack

In Zephyr's experimental USB host stack CONFIGUSBHOSTSTACK, usbhdevicedisconnect subsys/usb/host/usbhdevice.c freed the root usbdevice slab object without clearing the cached pointer ctx-root. The bus removal handler devremovedhandler subsys/usb/host/usbhcore.c decides what to tear down solely fr...
