Linux kernel xusb.c file code issue vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A code issue vulnerability exists in the Linux kernel prior to version 5.17, which stems from the drivers/phy/tegra/xusb.c file incorrectly handling the return value of tegra_xusb_find_port_node. An attacker could exploit this vulnerability to cause availability to be affected.
