What is CVE-2025-22011?
CVE-2025-22011 is a medium-severity denial of service vulnerability in Linux kernel, published on 8 Apr 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In the Linux kernel, the following vulnerability has been resolved:
ARM: dts: bcm2711: Fix xHCI power-domain
During s2idle tests on the Raspberry CM4 the VPU firmware always crashes on xHCI power-domain resume:
root@raspberrypi:/sys/power# echo freeze > state [ 70.724347] xhci_suspend finished [ 70.727730] xhci_plat_suspend finished [ 70.755624] bcm2835-power bcm2835-power: Power grafx off [ 70.761127] USB: Set power to 0
[ 74.653040] USB: Failed to set power to 1 (-110)
This seems to be caused because of the mixed usage of raspberrypi-power and bcm2835-power at the same time. So avoid the usage of the VPU firmware power-domain driver, which prevents the VPU crash.
Which versions are affected by CVE-2025-22011?
It affects 1 product.
Products include Linux kernel.
How do I fix CVE-2025-22011?
Apply the vendor's patch.
