Executive Summary

This vulnerability is a memory leak in the Linux kernel's ath11k WiFi driver. Specifically, when the function ath11k_peer_find() fails, it does not properly release allocated cryptographic resources using crypto_free_shash(), leading to a memory leak. The fix involves adding the missing crypto_free_shash() call to prevent this leak.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing system instability if the leak is significant and persistent.

Mitigation Strategies

Update the Linux kernel to a version that includes the fix for the memory leak in ath11k_peer_rx_frag_setup, which adds the missing crypto_free_shash() call. This will prevent the memory leak caused when ath11k_peer_find() fails.
