CVE-2014-0998
Integer signedness error in the vt console driver (formerly Newcons) in FreeBSD 9.3 before p10 and 10.1 before p6 allows local users to cause a denial of service (crash) and possibly gain privileges via a negative value in a VT_WAITACTIVE ioctl call,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
