In the Linux kernel, the following vulnerability has been resolved: drm/dpmst: Handle torn-down topology gracefully in drmdpmsttopologyqueueprobe A hotplug or link-loss event can tear down the MST topology setting mgr-mststate = false and mgr-mstprimary = NULL concurrently with a caller invoking...

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 ...

CVE-2026-68093

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...
