CVSS: 8.2EPSS: 0%CPEs: 3EXPL: 1CVE-2022-40262 – The arbitrary write vulnerability in S3Resume2Pei leads to arbitrary code execution during PEI phase.
https://notcve.org/view.php?id=CVE-2022-40262
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 attacker can build a payload which can be injected into the SMRAM memory. This issue affects: Module name: S3Resume2Pei SHA256: 7bb29f05534a8a1e010443213451425098faebd45948a4642db969b19d0253fc Module GUID: 89E549B0-7CFE-449D-9BA3-10D8B2312D71 Un atacante potencial puede ejecutar un código arbitrario en el momento de la fase PEI e influir en las etapas de arranque posteriores. Esto puede conllevar a una omisión de mitigaciones, revelación del contenido de la memoria física, detección de cualquier secreto de cualquier Máquina Virtual (VM) y omisión del aislamiento de la memoria y de los límites informáticos confidenciales. • https://www.ami.com/security-center https://www.binarly.io/advisories/BRLY-2022-009 • CWE-123: Write-what-where Condition CWE-787: Out-of-bounds Write •
CVSS: 8.2EPSS: 0%CPEs: 5EXPL: 1CVE-2022-40261 – SMM memory corruption vulnerability in OverClockSmiHandler SMM driver
https://notcve.org/view.php?id=CVE-2022-40261
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 Un atacante puede explotar esta vulnerabilidad para elevar los privilegios del anillo 0 al anillo -2, ejecutar código arbitrario en el Modo de Administración del Sistema - un entorno más privilegiado que el sistema operativo (SO) y completamente aislado de él. • https://www.ami.com/security-center https://www.binarly.io/advisories/BRLY-2022-003 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
