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-2026-68212

The CVE affects the Linux kernel driver media: saa7134, specifically saa7134_video_init1. The issue is a memory leak risk caused by missing return-value checks on two saa7134_pgtable_alloc() calls and incomplete error handling when vb2_queue_init() for the VBI queue fails. If a pgtable allocation...
