Vulnerability Title
xhci: tegra: fix checked USB2 port number
Source: NVD (National Vulnerability Database)
Vulnerability Description
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. [ 116.923438] Unable to handle kernel paging request at virtual address 006c622f7665642f ...
