CVE-2022-40262 [HIGH] CWE-123 CVE-2022-40262: A potential attacker can execute an arbitrary code at the time of the PEI phase and influence the su A potential attacker can execute an arbitrary code at the time of the PEI phase 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 attack

CVE-2022-40261 [HIGH] CWE-120 CVE-2022-40261: An attacker can exploit this vulnerability to elevate privileges from ring 0 to ring -2, execute arb 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

CVE-2022-40246 [HIGH] CWE-123 CVE-2022-40246: A potential attacker can write one byte by arbitrary address at the time of the PEI phase (only duri 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 c

CVE-2022-26873 [HIGH] CWE-121 CVE-2022-26873: A potential attacker can execute an arbitrary code at the time of the PEI phase and influence the su A potential attacker can execute an arbitrary code at the time of the PEI phase 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 attack
