CVE-2024-0213

Privilege escalation via unchecked message-bus file input

Published Jan 9, 2024 · Updated Jun 17, 2025

Buffer overflow in Trellix Agent before 5.8.1 allows local users on Linux and macOS to gain root privileges or crash its service. The TA service fails to validate data written to point-product message-bus socket files before processing it, corrupting memory in the root process. A local account is required; successful exploitation can elevate privileges, interrupt the service, and disable event reporting to ePO.
