CVE-2020-24509

Privilege escalation via undisclosed control-flow flaw

Published Jun 9, 2021 · Updated Aug 4, 2024

Insufficient control-flow management in Intel SPS firmware allows local users with high privileges to escalate privileges in the SPS subsystem. Intel identifies only an unspecified subsystem and has not disclosed the control-flow operation or input that is handled incorrectly. Exploitation requires high privileges and local access and permits protected-state modification across a security boundary, with limited data exposure and no reported service interruption.
