CVE-2023-22327

Privileged information disclosure via firmware out-of-bounds write

Published Nov 14, 2023 · Updated Oct 15, 2024

Out-of-bounds write in Intel FPGA Arm Trusted Firmware before 2.8.1 allows local users with high privileges to disclose information. The flaw resides in the Arm Trusted Firmware running on the HPS, but Intel has not published the affected routine, input, or unchecked write operation. Exploitation requires local access and high privileges, and the vendor describes information disclosure rather than service interruption.
