CVE-2017-3748
On Lenovo VIBE mobile phones, improper access controls on the nac_server component can be abused in conjunction with CVE-2017-3749 and CVE-2017-3750 to elevate privileges to the root user (commonly known as 'rooting' or "jail breaking" a device).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
