CVE-2026-98863

The Linux kernel contains a vulnerability in the KVM x86 component related to how GET_NESTED_STATE_PAGES is handled. If obtaining nested pages fails during the KVM_RUN path, the request was not re-pended before exiting to userspace. This could allow KVM to re-enter L2 with stale, unpinned PFNs fr...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.5 contains a security vulnerability. This vulnerability arises from the fact that the KVM device’s ioctl command is not serialized with KVMRUN. As a result, when concurrent vCPUs are migrated, operations involving IMSIC attributes may use outdated physical CPUs and HGEI...
