Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
phy: tegra: xusb: Clear the driver reference in usb-phy dev<br />
<br />
For the dual-role port, it will assign the phy dev to usb-phy dev and<br />
use the port dev driver as the dev driver of usb-phy.<br />
<br />
When we try to destroy the port dev, it will destroy its dev driver<br />
as well. But we did not remove the reference from usb-phy dev. This<br />
might cause the use-after-free issue in KASAN.
