Description
Return of pointer value outside of expected range in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A flaw in Intel BIOS firmware allows a privileged user to escalate privileges via a pointer value outside expected range.
Vulnerability
The vulnerability resides in the BIOS firmware of certain Intel processors. It involves a return of a pointer value that falls outside the expected range, which can be triggered by a privileged user. Affected processor models and firmware versions are detailed in Intel SA-00601 [1].
Exploitation
An attacker must have local access and possess privileged user status (e.g., administrator or root) to exploit this issue. The exploitation sequence involves manipulating the pointer return value to cause an out-of-bounds condition, leading to privilege escalation.
Impact
Successful exploitation allows the attacker to escalate privileges, potentially gaining higher-level access or bypassing security controls within the system.
Mitigation
Intel has released firmware updates to address this vulnerability. Users should update their BIOS to the latest version provided by their system manufacturer. Refer to Intel SA-00601 [1] for specific fixed versions and instructions.
