CVE-2023-49144

Privileged information disclosure via out-of-bounds read

Published Aug 14, 2024 · Updated Aug 16, 2024

Out-of-bounds read in Intel OpenBMC Firmware before egs-1.15-0 or bhs-0.27 allows local users with high privileges to disclose data. Intel has not disclosed the affected component, input, or operation that causes the firmware to read beyond a buffer boundary. Exploitation requires high-privilege local access to the BMC; the published impact is information disclosure, with no availability impact.
