igvm

igvm 이 프로젝트는 IGVMIndependent Guest Virtual Machine 파일 형식의 본거지입니다. 형식 사양은 igvmdefs 크레이트에서 찾을 수 있으며, 바이너리 형식의 Rust 구현체는 igvm 크레이트에 있습니다. IGVM 파일 형식은 AMD SEV-SNP 및 Intel TDX와 같은 다양한 격리 기술을 지원하면서, 모든 가상화 스택에서 가상 머신을 실행하는 데 필요한 모든 정보를 캡슐화하도록 설계되었습니다. 개념적으로 이 파일 형식은 파일을 생성한 도구에 의해 만들어진 명령 집합이며, 로더가 초기...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: making the apf token non-zero to fix the bug In the current async pagefault logic, when a page is ready, KVM relies on kvmarchcandequeuepagepresent to determine whether to deliver a READY event to the Guest. This...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

CVE-2026-49744

Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Out of bounds accesses triggered by malware introduced to a Guest KMD could allow privilege escalation which escapes...

CVE-2026-63940

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV module. This vulnerability occurs because the system does not properly handle Port I/O requests with a length of zero. An attacker, potentially from a guest virtual machine, could exploit...

SUSE: CVE-2026-3842: SUSE Linux Security Advisory

A flaw was found in QEMU. This vulnerability allows a local attacker within a guest virtual machine to write data beyond its allocated memory. This occurs when cpuphysicalmemorymap returns a shorter length than expected, leading to an out-of-bounds write. Successful exploitation could result in...
