CVE-2026-98470

The Linux kernel contains a vulnerability in the KVM subsystem on arm64 architectures. The function kvm_pkvm_ioctl_allowed() issues a WARNING when kvm_get_cap_for_kvm_ioctl() fails to find an ioctl number in vm_ioctl_caps[]. Because kvm_arch_vm_ioctl() calls this check for unhandled numbers, an a...

CVE-2026-89981

CVE-2026-89981 affects the Linux kernel on arm64 platforms. The __cpuinfo_store_cpu() function reads the GMID_EL1 register based on the raw ID_AA64PFR1_EL1 value, even when the kernel has MTE disabled (CONFIG_ARM64_MTE=n or arm64.nomte). In a pKVM (protected KVM) environment, KVM sets HCR_EL2.TID...
