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...

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...

hw: amd: Instruction raise #VC exception at exit

A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...

SUSE CVE-2021-26339

A bug in AMD CPU's core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers...
