CVE-2025-58150

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...

CVE-2025-58150

CVE-2025-58150 affects the Xen hypervisor (shadow mode tracing code) where per-CPU variables are written with guest-controlled data. The writes can exceed the destination variable, and bounding is missing, enabling memory corruption. Public advisories (XSA-477) and multiple distro updates (Fedora...
