CVE-2023-52874
In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Zero out the missing RSI in TDXHYPERCALL macro In the TDXHYPERCALL asm, after the TDCALL instruction returns from the untrusted VMM, the registers that the TDX guest shares to the VMM need to be cleared to avoid...
CVE-2023-52874
CVE-2023-52874 (Linux kernel, x86/tdx): the vulnerability stems from an omission in the TDX_HYPERCALL path where RSI was not cleared when returning from TDCALL, risking speculation of VMM-provided values after the guest legally shares registers with the untrusted VMM. The issue originates from a ...
