CVE-2026-68093
A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine. When a virtual CPU vCPU is scheduled out and its physical CPU pCPU undergoes a hotplug cycle offline and then online, the vCPU might resume with an Address Space Identifier ASID that has been reassigned to another vCPU from ...
UBUNTU-CVE-2026-68093
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Bump asidgeneration on CPU online to avoid ASID collision after hotplug If a vCPU stays scheduled out or blocked while the last pCPU it ran on goes through a hotplug cycle online-offline-online, and the vCPU then resume...
CVE-2026-68093
The CVE describes a Linux kernel KVM SVM issue where ASIDs can collide after a CPU hotplug cycle. If a vCPU resumes on the same pCPU after online/offline/online, it may reuse an ASID that was assigned to a different vCPU, causing stale TLB translations and NPT faults. The root cause is svm_enable...
