Executive Summary

This vulnerability exists in the Linux kernel's amdxdna driver, specifically in the amdxdna_ubuf_map() function. The function allocates memory for scatter-gather (sg) and internal sg table structures but does not properly free this memory if certain subsequent operations fail. This leads to a memory leak.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion. This may result in system instability or crashes if the leak is significant and not mitigated.
