SMM memory corruption vulnerability in OverClockSmiHandler SMM driver

An attacker can exploit this vulnerability to elevate privileges from ring 0 to ring -2, execute arbitrary code in System Management Mode - an environment more privileged than operating system (OS) and completely isolated from it. Running arbitrary code in SMM additionally bypasses SMM-based SPI flash protections against modifications, which can help an attacker to install a firmware backdoor/implant into BIOS. Such a malicious firmware code in BIOS could persist across operating system re-installs. Additionally, this vulnerability potentially could be used by malicious actors to bypass security mechanisms provided by UEFI firmware (for example, Secure Boot and some types of memory isolation for hypervisors). This issue affects: Module name: OverClockSmiHandler SHA256: a204699576e1a48ce915d9d9423380c8e4c197003baf9d17e6504f0265f3039c Module GUID: 4698C2BD-A903-410E-AD1F-5EEF3A1AE422

Arbitrary write vulnerability in SbPei module leads to arbitrary code execution during PEI phase.

A potential attacker can write one byte by arbitrary address at the time of the PEI phase (only during S3 resume boot mode) and influence the subsequent boot stages. This can lead to the mitigations bypassing, physical memory contents disclosure, discovery of any secrets from any Virtual Machines (VMs) and bypassing memory isolation and confidential computing boundaries. Additionally, an attacker can build a payload which can be injected into the SMRAM memory. This issue affects: Module name: SbPei SHA256: d827182e5f9b7a9ff0b9d3e232f7cfac43b5237e2681e11f005be627a49283a9 Module GUID: c1fbd624-27ea-40d1-aa48-94c3dc5c7e0d
