Local privilege escalation via improper buffer restrictions
Published Jun 15, 2020 · Updated Aug 4, 2024
Improper buffer restrictions in Intel CSME before 12.0.64, 13.0.32, 14.0.33, and 14.5.12 allow local users to elevate privileges. Intel has not published the affected subsystem, buffer operation, or input that reaches the improper restriction. Exploitation requires authenticated local access and can also disclose information or interrupt service, with no network attack path reported.
