CVE-2026-74520 iommu/iommufd: Fix IOPF group ownership UAF

In the Linux kernel, the following vulnerability has been resolved: iommu/iommufd: Fix IOPF group ownership UAF iopfgroupalloc links each last-page IOPF group into the generic IOPF pending list before invoking the domain fault handler. iommufdfaultiopfhandler also queued an accepted group in the...

CVE-2026-74519

The CVE-2026-74519 issue affects the Linux kernel's pinctrl Devicetree map handling. When dt_remember_or_free_map() duplicates dev_name for each map entry, a failure in kstrdup_const() could lead dt_free_map() to free dev_name for all entries, including uninitialized ones, causing a double-free u...

CVE-2026-74516

The CVE-2026-74516 entry concerns the Linux kernel KVM: SVM flaw where, if AVIC is inhibited while L2 is active, KVM may run L1 with AVIC disabled but with x2APIC MSR intercepts disabled. This allows L1 to access most of the host APIC state, send arbitrary interrupts, change task priority, and po...

CVE-2026-74517

CVE-2026-74517 affects the Linux kernel KVM/x86 code. The vulnerability arises from not canceling and flushing the I/O APIC delayed EOI handling during VM destruction, allowing a use-after-free in kvm_irq_delivery_to_apic_fast if vCPUs have already been destroyed. The issue is resolved by ensurin...
