CVE-2026-29645

NEMU OpenXiangShan/NEMU before v2025.12.r2 contains an improper instruction-validation flaw in its RISC-V Vector RVV decoder. The decoder does not correctly validate the funct3 field when decoding vsetvli/vsetivli/vsetvl, allowing certain invalid OP-V instruction encodings to be misinterpreted an...

EUVD-2025-203736

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Don't skip unrelated instruction if INT3/INTO is replaced When re-injecting a soft interrupt from an INT3, INT0, or select INTn instruction, discard the exception and retry the instruction if the code stream is changed...

CVE-2025-68259

Summary: In the Linux kernel’s KVM/SVM path, re-injecting a soft interrupt when replacing INT3/INT0/INTn can lead to decoding a different instruction and thus a wrong next RIP. This can clobber guest state and trigger a guest panic (e.g., Oops: int3) if the RIP lookup uses the incorrect instructi...

PT-2025-51672

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw within the KVM SVM component. Specifically, when re-injecting a soft interrupt from an INT3 instruction, the system may discard the exception and retry t...

CVE-2024-47727 x86/tdx: Fix "in-kernel MMIO" check

In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix "in-kernel MMIO" check TDX only supports kernel-initiated MMIO operations. The handlemmio function checks if the VE exception occurred in the kernel and rejects the operation if it did not. However, userspace can...

CVE-2009-1542: Undefined Security Weakness

The Virtual Machine Monitor VMM in Microsoft Virtual PC 2004 SP1, 2007, and 2007 SP1, and Microsoft Virtual Server 2005 R2 SP1, does not enforce CPU privilege-level requirements for all machine instructions, which allows guest OS users to execute arbitrary kernel-mode code and gain privileges...
