CVE-2019-19052
A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-fb5be6a7b486.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
