Insufficient control flow management in the Alias Checking Trusted Module (ACTM) firmware for some Intel(R) Xeon(R) processors may allow a privileged user to potentially enable escalation of privilege via local access.

Improper handling of overlap between protected memory ranges for some Intel(R) Xeon(R) 6 processor with Intel(R) TDX may allow a privileged user to potentially enable escalation of privilege via local access.

Privilege Escalation via Incorrect Firmware Control Flow in Intel Xeon Processors

Always-incorrect control flow implementation in some firmware for some Intel(R) Xeon(R) processors may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.

Insufficient control flow management in UEFI firmware for some Intel(R) Xeon(R) Processors may allow an authenticated user to enable denial of service via local access.

Sequence of processor instructions leads to unexpected behavior in the Intel(R) DSA V1.0 for some Intel(R) Xeon(R) Processors may allow an authenticated user to potentially enable denial of service via local access.

Improper buffer restrictions for some Intel(R) Xeon(R) Processor firmware with SGX enabled may allow a privileged user to potentially enable escalation of privilege via local access.

Insufficient granularity of access control in the OOB-MSM for some Intel(R) Xeon(R) 6 Scalable processors may allow a privileged user to potentially enable escalation of privilege via adjacent access.

Sequence of processor instructions leads to unexpected behavior for some Intel(R) Xeon(R) 6 Scalable processors may allow an authenticated user to potentially enable escalation of privilege via local access

Missing reference to active allocated resource for some Intel(R) Xeon(R) processors may allow an authenticated user to potentially enable denial of service via local access.

Insufficient control flow management for some Intel(R) Xeon Processors may allow an authenticated user to potentially enable denial of service via local access.

Protection mechanism failure in some 3rd, 4th, and 5th Generation Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.
