A vulnerability in the Linux kernel's KVM arm64 implementation related to fine-grained undefined instruction (UNDEF) handling without FEAT_FGT has been resolved. The issue involved incorrect gating of fine-grained trap (FGT) configuration insertion, which could cause spurious warnings and improper trap handling in certain hardware configurations. The fix ensures that fine-grained undefined instruction traps (FGUs) are always applied correctly regardless of hardware support for FEAT_FGT, preventing unexpected behavior during virtualization.
