CVE-2024-23907

Privilege escalation via uncontrolled compiler search path

Published Aug 14, 2024 · Updated Aug 14, 2024

Uncontrolled search path in Intel High Level Synthesis Compiler before 23.4 allows local users to escalate privileges during compilation. The advisory identifies an uncontrolled search path but does not disclose the affected compiler lookup or the code object it loads. Exploitation requires low-privilege local access, high-complexity conditions, and active interaction by another user; successful execution grants the planted code the victim process's privileges.
