hw: amd: Instruction raise #VC exception at exit
A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...
