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...
