Insufficient input parameter sanitization in AMD Secure Processor (ASP) Boot Loader (legacy recovery mode only) could allow an attacker to write out-of-bounds to corrupt Secure DRAM potentially resulting in denial of service.
Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution.
Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity.
Insufficient or Incomplete Data Removal in Hardware Component in SEV firmware doesn't fully flush IOMMU. This can potentially lead to a loss of confidentiality and integrity in guest memory.
Improper handling of error condition during host-induced faults can allow a local high-privileged attack to selectively drop guest DMA writes, potentially resulting in a loss of SEV-SNP guest memory integrity
A use after free in the SEV firmware could allow a malicous hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent potentially resulting in loss of integrity.
Insufficient Granularity of Access Control in SEV firmware can allow a privileged attacker to create a SEV-ES Guest to attack SNP guest, potentially resulting in a loss of confidentiality.
Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity.
Missing Checks in certain functions related to RMP initialization can allow a local admin privileged attacker to cause misidentification of I/O memory, potentially resulting in a loss of guest memory integrity
Improper handling of overlap between the segmented reverse map table (RMP) and system management mode (SMM) memory could allow a privileged attacker corrupt or partially infer SMM memory resulting in loss of integrity or confidentiality.
Improper access control in secure encrypted virtualization (SEV) could allow a privileged attacker to write to the reverse map page (RMP) during secure nested paging (SNP) initialization, potentially resulting in a loss of guest memory confidentiality and integrity.
Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution.
Improper Initialization within the AMD Secure Encrypted Virtualization (SEV) firmware can allow an admin privileged attacker to corrupt RMP covered memory, potentially resulting in loss of guest memory integrity
Improper Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of integrity.
Insufficient Granularity of Access Control in SEV firmware could allow a privileged user with a malicious hypervisor to create a SEV-ES guest with an ASID in the range meant for SEV-SNP guests potentially resulting in a partial loss of confidentiality.
Improper access control in AMD Secure Encrypted Virtualization (SEV) firmware could allow a malicious hypervisor to bypass RMP protections, potentially resulting in a loss of SEV-SNP guest memory integrity.
The Star Review Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.2. This is due to missing nonce validation on the settings page. This makes it possible for unauthenticated attackers to update the plugin's CSS settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Write what were condition within AMD CPUs may allow an admin-privileged attacker to modify the configuration of the CPU pipeline potentially resulting in the corruption of the stack pointer inside an SEV-SNP guest.
