hw: cpu: Intel: Stale Data Read from legacy xAPIC vulnerability

Improper isolation of shared resources in some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

Hardware debug modes and processor INIT setting that allow override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel(R) TXT may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

hw: cpu: intel: Intra-Mode BTI

Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.

hw: cpu: intel: Branch History Injection (BHI)

Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.

Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.

Out-of-bounds read in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via adjacent access.

Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable denial of service via local access.

Improper input validation for some Intel(R) PROSet/Wireless WiFi, Intel vPro(R) CSME WiFi and Killer(TM) WiFi products may allow unauthenticated user to potentially enable denial of service via local access.

hw: Intel: Improper initialization in TXT SINIT ACM may cause escalation privilege.

Improper initialization in the Intel(R) TXT SINIT ACM for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.

A stack buffer overflow vulnerability discovered in AsfSecureBootDxe in Insyde InsydeH2O with kernel 5.0 through 5.5 allows attackers to run arbitrary code execution during the DXE phase.
