USN-8888-2 linux-azure-7.0, linux-azure-fde-7.0 vulnerabilities
It was discovered that some AMD processors did not properly perform Reverse Map Table RMP checks when the IOMMU accessed certain host buffers. A local attacker with hypervisor access could possibly use this to trigger an out-of-bounds condition and compromise the integrity of SEV-SNP guest memory...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15
In the Linux kernel before version 6.9, a trusted-to-non-trusted hypervisor can inject Virtual Interrupt 29 VC at any point in time and can trigger its handler. This affects AMD SEV-SNP and AMD SEV-ES...
AlmaLinux 9.2 [TuxCare] Security Update: iwl100-firmware / iwl1000-firmware / iwl105-firmware / etc Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2025:1740470712)
The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1740470712 advisory. - IOMMU improperly handles certain special address ranges with invalid device table entries DTEs, which may allow an attacker with...
INTCC: A Framework for Interactive Confidential Computing
Confidential computing leverages Trusted Execution Environments TEEs to ensure the confidentiality and integrity of data in use. However, TEEs rely on remote attestation to guarantee the integrity of their initial memory state. This model is fundamentally at odds with interactive development...
CVE-2026-100839
Contrast is a confidential-computing runtime for Kubernetes. In versions before 1.18.0, the guest kernel's ACPI/AML handling is vulnerable to an AML injection attack "BadAML". ACPI tables containing AML bytecode are passed from the untrusted host QEMU to the guest firmware OVMF and on to the Linu...
