Out-of-bounds write in the BIOS authenticated code module for some Intel® Processors may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2021-33124)
Impact
A local attacker logged in as a privileged user can exploit the vulnerability to potentially enable escalation of privileges.
The following F5 hardware platforms are vulnerable to CVE-2021-33124:
For more information, refer to K9476: The F5 hardware/software compatibility matrix and K86001294: F5OS hardware/software support matrix.
All versions of Virtual Edition (VE) for the BIG-IP and BIG-IQ products are potentially impacted if the processors underlying the VE installations are affected. Microcode updates from Intel are available to address this issue but must be applied at the hardware level, which is outside the scope of the ability of F5 to support or patch.
