CVE-2022-36382

Denial of service via out-of-bounds firmware write

Published Feb 16, 2023 · Updated Jan 27, 2025

Out-of-bounds write in Intel E810 firmware before 1.7.0.8 and 700 Series firmware before 9.101 allows local users to cause denial of service. Intel identifies the affected locus as Ethernet controller firmware but does not disclose the responsible routine, attacker-controlled input, or missing bounds check. High privileges and local access are required; Intel does not state whether the resulting interruption is a hang, reset, or other loss of adapter service.
