Executive Summary

This vulnerability is a reference leak in the Linux kernel's RDMA core related to GID entries. Specifically, when an Address Handle (AH) creation request fails, the system did not properly release the sgid_attr, causing a GID entry reference leak in the GID table. The fix ensures that sgid_attr is released properly to avoid this leak.

Impact Analysis

The impact of this vulnerability is a resource leak in the kernel's RDMA subsystem, which could lead to increased memory usage or exhaustion of GID entries over time, potentially degrading system performance or stability.
