CVE-2019-19529
In the Linux kernel before 5.3.11, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/net/can/usb/mcba_usb.c driver, aka CID-4d6636498c41.
Does this matter?
Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.
