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-2026-68298

A flaw was found in the Linux kernel's drm/xe/vm module. During the creation of a virtual machine VM, an error in resource allocation could lead to a Shared Virtual Memory SVM resource leak. This occurs because the kernel's resource deallocation functions are not consistently called when an error...

CVE-2026-68298

CVE-2026-68298 concerns the Linux kernel drm/xe/vm code. The vulnerability stems from an error path where, after a failed drm_gpuvm_resv_object_alloc(), resources allocated by xe_svm_init() could leak because xe_svm_fini() and xe_svm_close() were not always invoked for non-fault-mode VMs. The fix...
