CVE-2025-1713 (GCVE-0-2025-1713)

Vulnerability from cvelistv5 – Published: 2025-07-17 13:59 – Updated: 2025-07-17 14:21

Summary

When setting up interrupt remapping for legacy PCI(-X) devices, including PCI(-X) bridges, a lookup of the upstream bridge is required. This lookup, itself involving acquiring of a lock, is done in a context where acquiring that lock is unsafe. This can lead to a deadlock.

Severity ?

7.5 (High)
