CVE-2026-31759

A flaw was found in the Linux kernel's USB ULPI UTMI+ Low Pin Interface driver. An error in the ulpiregisterinterface function's cleanup path can lead to a double free vulnerability. This occurs when deviceregister fails, causing the ulpi structure to be freed twice. A local attacker could...

CVE-2026-31727

A flaw was found in the Linux kernel's USB gadget subsystem, specifically within the uether module. A local user can exploit this vulnerability by using a userspace tool to query a USB gadget interface during a specific detached state. This action can trigger a NULL pointer dereference, potential...

CVE-2026-31701

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA caiaq driver. This vulnerability arises from improper handling of Universal Serial Bus USB device references. When a USB device is disconnected, the driver may attempt to access memory that has already been freed, a...

CVE-2026-31757

In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: Fix URB memory leak on submit failure When usbsubmiturb fails in usbioprobe, the previously allocated URB is never freed, causing a memory leak. Fix this by jumping to errfreeurb label to properly release the UR...

CVE-2026-31758

In the Linux kernel, the following vulnerability has been resolved: usb: usbtmc: Flush anchored URBs in usbtmcrelease When calling usbtmcrelease, pending anchored URBs must be flushed or killed to prevent use-after-free errors e.g. in the HCD giveback path. Call usbtmcdrawdown to allow anchored...

CVE-2026-31701

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: take a reference on the USB device in createcard The caiaq driver stores a pointer to the parent USB device in cdev-chip.dev but never takes a reference on it. The card's privatefree callback, sndusbcaiaqcardfree, ca...

CVE-2026-31760 gpib: lpvo_usb: fix memory leak on disconnect

In the Linux kernel, the following vulnerability has been resolved: gpib: lpvousb: fix memory leak on disconnect The driver iterates over the registered USB interfaces during GPIB attach and takes a reference to their USB devices until a match is found. These references are never released which...

CVE-2026-31760

The CVE-2026-31760 issue affects the Linux kernel GPIB gpib: lpvo_usb driver, where the driver incorrectly retains references to USB devices during GPIB attach, causing a memory leak on disconnect. The root cause is not releasing those references after attaching, leading to resource retention. Th...

CVE-2026-31757

CVE-2026-31757 affects the Linux kernel USB subsystem (usbio). The issue is a memory leak where, if usb_submit_urb() fails during device probing (usbio_probe()), the previously allocated URB is not freed. The fix directs control flow to an error path (err_free_urb) to properly release the URB and...
