Description OSIDB Bzimport 2025-12-24 14:05:24 UTC
In the Linux kernel, the following vulnerability has been resolved:

phy: tegra: xusb: Clear the driver reference in usb-phy dev

For the dual-role port, it will assign the phy dev to usb-phy dev and
use the port dev driver as the dev driver of usb-phy.

When we try to destroy the port dev, it will destroy its dev driver
as well. But we did not remove the reference from usb-phy dev. This
might cause the use-after-free issue in KASAN.
