kernel: Intel firmware update for improper isolation of shared resources

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

hw: Intel: Improper input validation in the BIOS firmware may cause escalation privilege

Improper input validation in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege 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.

Arbitrary Memory Disclosure through CPU Side-Channel Attacks (Retbleed)

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.

AMD Speculative execution with Floating-Point Value Injection

Potential floating point value injection in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution with incorrect floating point results, may cause the use of incorrect data from FPVI and may result in data leakage.

AMD Speculative Code Store Bypass

Potential speculative code store bypass in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution of overwritten instructions, may cause an incorrect speculation and could result in data leakage.

Improper input validation in the Intel(R) SGX SDK applications compiled for SGX2 enabled processors may allow a privileged user to potentially escalation of privilege via local access.

kernel: hw: Insecure default variable initialization for the Intel BSSA DFT feature

Insecure default variable initialization for the Intel BSSA DFT feature may allow a privileged user to potentially enable an escalation of privilege via local access.
