Deadlock Risk in Legacy PCI Bridge Implementation by Xen Project
CVE-2025-1713
7.5HIGH
What is CVE-2025-1713?
This vulnerability arises from the improper handling of interrupt remapping for legacy PCI and PCI-X devices, including PCI-X bridges. The process requires a lookup of the upstream bridge, which involves acquiring a lock in an unsafe context. This can result in a deadlock, hindering system operations and posing risks to stability and performance for users of the affected Xen Hypervisor versions.
