CVE-2017-5721
Insufficient input validation in system firmware for Intel NUC7i3BNK, NUC7i3BNH, NUC7i5BNK, NUC7i5BNH, NUC7i7BNH versions BN0049 and below allows local attackers to execute arbitrary code via manipulation of memory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
