CVE-2026-31759 usb: ulpi: fix double free in ulpi_register_interface() error path

In the Linux kernel, the following vulnerability has been resolved: usb: ulpi: fix double free in ulpiregisterinterface error path When deviceregister fails, ulpiregister calls putdevice on ulpi-dev. The device release callback ulpidevrelease drops the OF node reference and frees ulpi, but the...

CVE-2026-31759

CVE-2026-31759 affects the Linux kernel USB ULPI path (usb: ulpi) where a double free could occur in ulpi_register_interface() after a failed device_register(), because the error path freed ulpi twice. The root cause is a missing delegation of cleanup to put_device() via ulpi_dev_release(), preve...

CVE-2026-31753

CVE-2026-31753 affects the Linux kernel’s auxdisplay/line-display path. A NULL dereference in linedisp_release can occur if the enclosing linedisp object has already been detached when the release callback runs, causing a crash while freeing display resources. The fix retrieves the enclosing obje...

CVE-2026-31751

In the Linux kernel, the following vulnerability has been resolved: comedi: dt2815: add hardware detection to prevent crash The dt2815 driver crashes when attached to I/O ports without actual hardware present.

CVE-2026-31745 reset: gpio: fix double free in reset_add_gpio_aux_device() error path

In the Linux kernel, the following vulnerability has been resolved: reset: gpio: fix double free in resetaddgpioauxdevice error path When auxiliarydeviceadd fails, resetaddgpioauxdevice calls auxiliarydeviceuninitadev. The device release callback resetgpioauxdevicerelease frees adev, but the...

CVE-2026-31745

CVE-2026-31745 affects the Linux kernel GPIO reset path. The double-free occurs in reset_add_gpio_aux_device(): if __auxiliary_device_add() fails, the code calls auxiliary_device_uninit(adev), the device release callback frees adev, but the error path then frees adev again with kfree(adev). The f...
