CVE-2026-72280
CVE-2026-72280 concerns the Linux kernel KVM on arm64. The vulnerability arises from a logic issue where a guest could write to the ZCR_EL2 sysreg alias in a nested context if FEAT_NV2 is advertised to the L1 hypervisor. The fix is to drop the bogus WARN that could lead to a hyp_panic once hyp ve...
