CVE-2025-58150

x86: buffer overrun with shadow paging + tracing

Shadow mode tracing code uses a set of per-CPU variables to avoid
cumbersome parameter passing.  Some of these variables are written to
with guest controlled data, of guest controllable size.  That size can
be larger than the variable, and bounding of the writes was missing.
