The Telematics Control Unit (aka Telematic Communication Box or TCB), when present on BMW vehicles produced in 2012 through 2018, allows a remote attack via a cellular network.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
