CVE-2024-34776

Local privilege escalation via out-of-bounds write

Published Nov 13, 2024 · Updated Nov 14, 2024

Out-of-bounds write in Intel SGX SDK for Linux before 2.24 allows local users to escalate privileges through local access. Intel has not published the affected component, memory operation, or attacker-controlled input that crosses the buffer boundary. Exploitation requires authenticated local access and high-complexity conditions, and Intel reports bounded confidentiality, integrity, and availability effects.
