The Linux Kernel, the operating system core itself. Security Fixes: An out-of-boundsOOB memory access vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfxkms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128 or Dxxx'. This flaw allows a local attacker...
The vulnerability in the implementation of the SNP_INIT command during the loading of microprogramming software for AMD processors allows a attacker to influence the integrity of the protected information.
The vulnerability of the SNPINIT implementation in the loading of microprogramming software for AMD processors is related to insufficient validation of input data. Exploiting this vulnerability can allow an attacker to influence the integrity of the protected information...
SUSE CVE-2019-19577
An issue was discovered in Xen through 4.12.x allowing x86 AMD HVM guest OS users to cause a denial of service or possibly gain privileges by triggering data-structure access during pagetable-height updates. When running on AMD systems with an IOMMU, Xen attempted to dynamically adapt the number ...
SUSE CVE-2020-12965
When combined with specific software sequences, AMD CPUs may transiently execute non-canonical loads and store using only the lower 48 address bits potentially resulting in data leakage...
SUSE CVE-2021-26335
Improper input and range checking in the AMD Secure Processor ASP boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution...

Name of the Vulnerable Software and Affected Versions: System Management Mode SMM affected versions not specified Description: The issue is related to the failure to validate inputs in SMM, which may allow an attacker to create a mishandled error, leaving the DRTM UApp in a partially initialized...
AMD Platform Security Processor 竞争条件问题漏洞
AMD Platform Security Processor is a security processor from AMD. AMD Platform Security Processor suffers from a Competitive Conditions Issue vulnerability, which stems from a vulnerability that can be exploited by an attacker to exploit multiple vulnerabilities in AMD processors...
The vulnerability of AMD’s microprogrammed software for processors lies in the speculative execution of read and write operations that access memory using invalid non- canonical addresses. This allows a hacker to exploit the vulnerability to gain access to information about the CPU’s address space.
The vulnerability of AMD’s microprogramming software is related to speculative operations for reading and writing data to memory, involving the use of non- canonical addresses. Exploiting this vulnerability can allow an attacker to gain access to information about the CPU’s address space, by usin...
kernel: SVM nested virtualization issue in KVM (AVIC support)
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 "intctl" field, this issue could allow a malicious ...
