Generation of weak and predictable Initialization Vector (IV) in PMFW (Power Management Firmware) may allow an attacker with privileges to reuse IV values to reverse-engineer debug data, potentially resulting in information disclosure.

Incomplete cleanup in the ASP may expose the Master Encryption Key (MEK) to a privileged attacker with access to the BIOS menu or UEFI shell and a memory exfiltration vulnerability, potentially resulting in loss of confidentiality.

A hardcoded AES key in PMFW may result in a privileged attacker gaining access to the key, potentially resulting in internal debug information leakage.

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.

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

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.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet…

Weak permissions in the Vitis™ Unified installation path on local Windows machines could allow a low-privileged user to create arbitrary code, potentially resulting in binary hijacking.

Weak permissions in the Vitis™ Unified installation path on local Windows machines could allow a low-privileged user to achieve privileged escalation, potentially resulting in arbitrary code execution.

Bug in AMD K6 processor on Linux 2.0.x and 2.1.x kernels allows local users to cause a denial of service (crash) via a particular sequence of instructions, possibly related to accessing addresses outside of segments.

An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing the input of an arbitrary message, potentially leading to a loss of data integrity.

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: Check event before enable to avoid GPF On AMD machines cpuc->events[idx] can become NULL in a subtle race condition with NMI->throttle->x86_pmu_stop(). Check event for NULL in…

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue…

The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue.

The AMD ATI atidsmxx.sys 3.0.502.0 driver on Windows Vista allows local users to bypass the driver signing policy, write to arbitrary kernel memory locations, and thereby gain privileges via unspecified vectors, as demonstrated by "Purple Pill".

Drivers for certain display adapters, including (1) an unspecified ATI driver and (2) an unspecified Intel driver, might allow remote attackers to cause a denial of service (system crash) via a large JPEG image, as demonstrated in Internet Explorer using stoopid.jpg with a width…
