"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: arm64: Apply the fine-grained UNDEFs without FEAT_FGT\n\nFGUs don't actually require hardware support, so don't gate fgt trap\nconfig insertion on FGT. This is the only action required to allow FGUs\nalways, as kvm_calculate_traps() already computes the FGU bits with or\nwithout FEAT_FGT.\n\nThis also fixes a spurious WARN when a TLBI OS is run on a guest in vEL1\nwithout FEAT_TLBIOS on non FEAT_FGT hardware. In this configuration the\ncourse-grained HCR_EL2.TTLBOS trap reaches the handler handle_tlbi_el1(),\nwhich expects an EL1 TLBI only from vEL2. With FGUs enabled the UNDEF\nwill be injected without needing the specific handler.\n\n[oliver: Take Wei-Lin's suggested changelog]"
