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...

CVE-2026-68428 KVM: x86/mmu: Fix use-after-free on vendor module reload

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Fix use-after-free on vendor module reload mmudestroycaches destroys ptelistdesccache and mmupageheadercache, but leaves both pointers unchanged. The pointers live in kvm.ko, and therefore survive when a vendor modu...

CVE-2026-68427

CVE-2026-68427 affects the Linux kernel’s gpu: host1x component. The vulnerability arises in __host1x_bo_unpin(), which dereferences a memory mapping after it has been freed, causing a use-after-free. The cache outlives the mapping, so the correct approach is to reference the cache object instead...
