Out-of-bounds write in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable an escalation of privilege via local access.

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

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

Out-of-bounds write in IPv6 subsystem for Intel(R) AMT, Intel(R) ISM versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70, 14.0.45 may allow an unauthenticated user to potentially enable escalation of privileges via network access.

Out-of-bounds write for some Intel(R) QAT Windows software before version 2.6.0. within Ring 3: User Applications may allow an escalation of privilege. System software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Memory corruption in Intel Active Management Technology in Intel Converged Security Manageability Engine Firmware 6.x / 7.x / 8.x / 9.x / 10.x / 11.0 / 11.5 / 11.6 / 11.7 / 11.10 / 11.20 could be triggered by an attacker with local administrator permission on the system.

Out of bounds write in Intel(R) PROSet/Wireless WiFi products on Windows 10 may allow an authenticated user to potentially enable denial of service via local access.

In ConnMan through 1.41, remote attackers able to send HTTP requests to the gweb component are able to exploit a heap-based buffer overflow in received_data to execute code.

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).
