CVE-2023-26589

Local tool crash via use-after-free object access

Published Nov 14, 2023 · Updated Aug 30, 2024

Use-after-free in Intel Aptio V UEFI Firmware Integrator Tools for Intel NUC allows local users to crash an affected tool. Intel has not published the affected executable, function, freed object's lifetime, or input sequence that triggers the stale reference. An authenticated low-privileged local account is required, and successful exploitation interrupts availability without reported data disclosure or modification.
