CVE-2026-68429

A flaw was found in the Linux kernel's DisplayPort DP Multi-Stream Transport MST module. A race condition can occur during hotplug or link-loss events when the MST topology is being torn down while the drmdpmsttopologyqueueprobe function is called. This can lead to spurious kernel warnings and...

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...

SUSE 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

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

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...
