CVE-2025-23263

Guest privilege escalation and VLAN service interruption

Published Jul 17, 2025 · Updated Jul 24, 2025

Incorrect execution-assigned permissions in NVIDIA DOCA-Host and Mellanox OFED allow guest OS users to elevate privileges and disrupt a VLAN. The VGT+ feature assigns incorrect permissions during execution, but NVIDIA has not disclosed the affected operation or attacker-controlled input. Reachability requires a low-privileged guest VM, VGT+ enabled, and the host eSwitch in Legacy mode; impact is limited to VGT+ and includes VLAN service interruption.
