Vulnerabilidades

Memory corruption while redirecting log file to any file location with any file name.

Due to a code bug in Secure_TSC, SEV firmware may allow an attacker with high privileges to cause a guest to observe an incorrect TSC when Secure TSC is enabled potentially resulting in a loss of guest integrity.

Failure to initialize memory in SEV Firmware may allow a privileged attacker to access stale data from other guests.

Sharp NEC Displays (P403, P463, P553, P703, P801, X554UN, X464UN, X554UNS, X464UNV, X474HB, X464UNS, X554UNV, X555UNS, X555UNV, X754HB, X554HB, E705, E805, E905, UN551S, UN551VS, X551UHD, X651UHD, X841UHD, X981UHD, MD551C8) allows an attacker execute remote code by sending unintended parameters in http request.

A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information.

Memory corruption in WLAN Host while processing RRM beacon on the AP.

Memory corruption while sending an Assoc Request having BTM Query or BTM Response containing MBO IE.

Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity.

Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity.

Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality.

TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.

SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity.

Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service.

Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access.

Memory corruption in WLAN HAL while handling command streams through WMI interfaces.

Certain Lexmark devices (such as CS310) before 2023-08-25 allow XXE attacks, leading to information disclosure. The fixed firmware version is LW80.*.P246, i.e., '*' indicates that the full version specification varies across product model family, but firmware level P246 (or higher) is required to remediate the…

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.

A potential power side-channel vulnerability in some AMD processors may allow an authenticated attacker to use the power reporting functionality to monitor a program’s execution inside an AMD SEV VM potentially resulting in a leak of sensitive information.

Uncontrolled resource consumption in Series WAGO 750-3x/-8x products may allow an unauthenticated remote attacker to DoS the MODBUS server with specially crafted packets.

A stack-based buffer overflow in the ChangeFriendlyName() function of Belkin Smart Outlet V2 F7c063 firmware_2.00.11420.OWRT.PVT_SNSV2 allows attackers to cause a Denial of Service (DoS) via a crafted UPNP request.

Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious Uapp or ABL to send malformed or invalid syscall to the bootloader resulting in a potential denial of service and loss of integrity.

An attacker with a compromised ASP could possibly send malformed commands to an ASP on another CPU, resulting in an out of bounds write, potentially leading to a loss a loss of integrity.

Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution.
