kernel: KVM: SVM: Flush pages under kvm->lock to fix UAF in svm_register_enc_region()

A security vulnerability was identified in the Linux kernel's Kernel-based Virtual Machine subsystem KVM, specifically affecting the Secure Virtual Machine SVM feature used on AMD processors. The issue arises from a use-after-free condition in the svmregisterencregion function, which can lead to...

hw: amd: SMM Lock Bypass

A flaw was found in hw. Improper validation in a model-specific register MSR could allow a malicious program with ring0 access to modify the SMM configuration while the SMI lock is enabled. This issue can lead to arbitrary code execution...

kernel: Reserved fields in guest message responses may not be zero initialized

A flaw was found in some AMD CPUs where the guest message responses have not been zero-initialized. This issue may allow a local attacker with the ability to run arbitrary code on a container or virtual machine to discover sensitive information contained in the host system's memory...

This could potentially result in denial of service...

USN-6956-1 linux-azure, linux-azure-5.15, linux-azure-fde, linux-azure-fde-5.15 vulnerabilities

Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to...

AMD SEV-SNP 安全漏洞

AMD SEV-SNP is a secure encrypted virtualization firmware from UltraMicroelectronics AMD. A single key is used to encrypt system memory. AMD SEV-SNP suffers from a security vulnerability that stems from an improper restriction on write operations causing a malicious hypervisor to overwrite the...

UBUNTU-CVE-2024-42121

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check index msgid before read or write WHAT msgid is used as an array index and it cannot be a negative value, and therefore cannot be equal to MODHDCPMESSAGEIDINVALID -1. HOW Check whether msgid is valid before...

hw: amd: INVD instruction may lead to a loss of SEV-ES guest machine memory integrity problem

A flaw was found in some of AMD CPU's due to improper or unexpected behavior of the INVD. This issue may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU, potentially leading to a loss of guest virtual machine VM memory integrity...
