CVE-2020-1608
Receipt of a specific MPLS or IPv6 packet on the core facing interface of an MX Series device configured for Broadband Edge (BBE) service may trigger a kernel crash (vmcore), causing the device to reboot.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
