CVE-2023-52874
CVE-2023-52874 (Linux kernel) concerns x86/tdx: after TDCALL, RSI was not cleared when zeroing the guest-visible register bitmap in the TDX_HYPERCALL path. The description notes the RSI bit was present in the bitmap when first added, removed later, and subsequently not XORed back after a pop RSI ...
