Although the CVTSD2SS instruction uses only 8 bytes, if it overlaps page boundary, I think QEMU tries to access over the valid memory and crashes. -Steps to reproduce: -1. Compile this code -``` -void main() { - mmap(0x555555559000, 0x1000, flag, ~~, 0); - asm("cvtsd2ss xmm1, qword ptr [0x555555559ff8]"); -} -``` -2. Execute. QEMU crashes but CPU does not. -Additional information: -This bug is discovered by research conducted by KAIST SoftSec. |
