Impact

A local attacker with low privileges can trigger incorrect memory access to corrupt data, crash services, or potentially escalate privileges. They require existing local access on a host running the affected DPDK service.

Root cause

A double-offset bug in the DPDK lib/vhost log mapping calculation results in out-of-bounds or incorrect memory access.
