CVE-2026-98638

The Linux kernel contains a vulnerability in the KVM subsystem on arm64 architecture. Specifically, the function pkvm_vcpu_init_sve() fails to properly validate the host-provided sve_max_vl, clamping only the upper bound. This allows an invalid vector length to reach sve_state_size_from_vl(), tri...
