CVE-2026-72292

The CVE-2026-72292 issue in the Linux kernel affects KVM on s390 where kvm_s390_get_cmma_bits() allocates its output with vmalloc(), which does not zero pages. In the non-peek migration path, dat_get_cmma() reports a byte span from the first to the last dirty page, but __dat_get_cmma_pte() only w...

CVE-2026-72290

CVE-2026-72290 affects the Linux kernel KVM when running on s390. The issue is a GISC (guest ISC) refcount leak that occurs because kvm_s390_gisc_register() registers the GISC before pinning guest interrupt forwarding pages and allocating the AISB bit; on error, the unwind path did not unregister...

CVE-2026-72289

CVE-2026-72289 affects the Linux kernel (KVM on arm64) where vgic interrupt migration logic can mis-handle pending/active interrupts during lock-protected migrations. Specifically, vgic_prune_ap_list() drops ap_list_lock and irq_lock and rechecks only affinity, which can pass for an interrupt tha...
