Linux Kernel GS USB Vulnerability

The Linux kernel's gs_usb driver is responsible for handling USB device communication. This vulnerability allows an attacker to bypass security checks and potentially execute arbitrary code on the system by manipulating the USB protocol.

You're affected if you use a Linux kernel version that contains this vulnerability, specifically versions prior to 5.10.0-rc3. To check for affected kernels, run the following command: uname -r | grep "5.10". This is not specific to any particular USB device or hardware.

To fix this issue:

1. Update your Linux kernel to version 5.10.0-rc3 or later.
   You can download the latest stable kernel from kernel.org.

2. If you cannot update immediately, consider applying a patch manually:

3. First, identify the affected kernel version using uname -r | grep "5.10".
4. Then, apply the patch to your kernel source code.
5. Rebuild and install your updated kernel.
