 From https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-28388

usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel 
through 5.17.1 has a double free.

It was discovered that the 8 Devices USB2CAN interface implementation in the 
Linux kernel did not properly handle certain error conditions, leading to a 
double-free. A local attacker could possibly use this to cause a denial of 
service (system crash).
