CVE-2026-53340

CVE-2026-53340 affects the Linux kernel i2c: imx driver. The root cause is an inconsistency between clock disable and pinctrl state switching in runtime PM: in i2c_imx_runtime_suspend(), the clock is disabled before pinctrl_sleep state is selected, so if pinctrl_pm_select_sleep_state() fails the ...

SUSE CVE-2026-53123

In the Linux kernel, the following vulnerability has been resolved: md: wake raid456 reshape waiters before suspend During raid456 reshape, direct IO across the reshape position can sleep in raid5makerequest waiting for reshape progress while still holding an activeio reference. If userspace then...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An inconsistency exists in the runtime power management of the i2c imx driver. In the i2c imx runtime suspend function, the clock is disabled before the pinctrl state is switched to slee...

CVE-2026-10647

The USB CDC-NCM device class subsys/usb/devicenext/class/usbdcdcncm.c ignores the return value of usbdepenqueue in its ethernet transmit callback cdcncmsend. When the enqueue fails, the function still calls ksemtake&data-syncsem, KFOREVER, blocking on a completion semaphore that is only ever...

CVE-2026-10647

The CVE concerns the USB CDC-NCM driver (subsys/usb/device_next/class/usbd_cdc_ncm.c) in Zephyr. The code ignores the return value of usbd_ep_enqueue() in cdc_ncm_send(); when enqueue fails, it still calls k_sem_take(&data-sync_sem, K_FOREVER), waiting on a completion that is only signaled from t...

PT-2026-53748

Name of the Vulnerable Software and Affected Versions Zephyr versions prior to 4.4.0 Description The USB CDC-NCM device class contains a flaw where the cdc ncm send function ignores the return value of usbd ep enqueue. If the enqueue operation fails—which occurs when the USB bus is suspended,...

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: fix mismatch between power and frequency During DPU runtime suspend, calling devpmoppsetratedev, 0 drops the MMCX rail to MINSVS while the core clock frequency remains at its original highest rate. When runtime resum...

CVE-2026-53056

A flaw was found in the Linux kernel's Display Processing Unit DPU driver. During DPU runtime suspend, a mismatch can occur between the power rail voltage and the core clock frequency. This happens when the power management attempts to drop the voltage while the clock remains at its highest rate...
