CVE-2024-50075

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

xhci: tegra: fix checked USB2 port number

If USB virtualizatoin is enabled, USB2 ports are shared between all
Virtual Functions. The USB2 port number owned by an USB2 root hub in
a Virtual Function may be less than total USB2 phy number supported
by the Tegra XUSB controller.

Using total USB2 phy number as port number to check all PORTSC values
would cause invalid memory access.
