(from the System V Application Binary Interface - Linux Extensions") Intel CET uses two processor-specific program properties in NT_GNU_PROPERTY_TYPE_0: GNU_PROPERTY_X86_FEATURE_1_IBT to indicate that all executable sections are compatible with Indirect Branch Tracking, and GNU_PROPERTY_X86_FEATURE_1_SHSTK to indicate that sections are compatible with shadow stack. A later change should add decoding of the individual properties.
