CVE-2026-68428

The CVE describes a use-after-free in KVM’s x86/mmu related to vendor module reloads, where mmu_destroy_caches() leaves pointers to caches (pte_list_desc_cache and mmu_page_header_cache) in kvm.ko. When a vendor module unload occurs while kvm.ko remains loaded, a subsequent cache initialization c...
