CVE-2025-38455

CVE-2025-38455 is a Linux kernel/KVM vulnerability in the KVM: SVM path. The issue occurs during SEV{-ES} intra-host migration when a vCPU is being created (in-flight) on either source or destination VM, where SEV{-ES} state can be toggled to non-SEV{-ES} in the destination. This can lead to a cr...

CVE-2025-38396

The CVE-2025-38396 entry concerns the Linux kernel vulnerability where anon_inode_make_secure_inode() is exported to allow KVM guest_memfd to create anonymous inodes with proper security context, fixing a secretmem LSM bypass. The issue involved the S_PRIVATE flag not being cleared after alloc_an...

CVE-2025-38367

CVE-2025-38367 concerns the Linux kernel LoongArch KVM subsystem. The issue arises from a logic error where a modified index is reused as an array index when updating the EIOINTC_ENABLE register, creating an array index overflow condition. The vulnerability affects the kernel, with the descriptio...

CVE-2025-38351

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush In KVM guests with Hyper-V hypercalls enabled, the hypercalls HVCALLFLUSHVIRTUALADDRESSLIST and HVCALLFLUSHVIRTUALADDRESSLISTEX allow a guest to request...

CVE-2025-38351

CVE-2025-38351 affects the Linux kernel KVM component (x86) when Hyper-V hypercalls are enabled. The issue arises in PV TLB flush processing where non-canonical GVAs can reach INVVPID/INVLPGA paths, potentially triggering VM-Fail on Intel hardware (AMD may ignore). In practice, this can allow a g...
