CVE-2024-47735 records a Unknown severity vulnerability in RDMA/hns: Fix spin_unlock_irqrestore() called with IRQs enabled. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic), Siemens/RUGGEDCOM RST2428P (generic), Siemens/SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
