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, which triggers an array index error and out-of-bounds kernel memory access.

Security readout for executives and security teams

A flaw in FreeBSD's vt console driver could let a logged-in local user crash the system and may allow privilege gain. It affects FreeBSD 9.3 before p10 and 10.1 before p6. Business risk is highest where untrusted users have local shell or console access. Likely exposure is limited to affected FreeBSD 9.3 and 10.1 systems using the vt console driver. Internet-facing exposure is not indicated; the source bundle describes local-user exploitation only. Handle during normal vulnerability remediation unless affected systems support untrusted local users or critical operations. In those cases, accelerate patching because kernel crashes can disrupt availability and privilege escalation is possible. Mitigation focus: Apply FreeBSD 9.3 p10 or 10.1 p6 or later vendor updates.; Review FreeBSD-EN-15:01.vt for the official remediation path.; Reduce untrusted local user access on affected systems until patched..
