Linux Kernel Memory Leak Vulnerability in wl1251 WiFi Driver

A memory leak vulnerability has been identified in the Linux kernel's wl1251 WiFi driver. The issue arises when the driver dequeues a socket buffer (skb) from the transmission queue (tx_queue) but fails to process it due to a timeout error. As a result, the skb is lost, leading to a memory leak. The vulnerability has been addressed by modifying the driver to requeue the skb back to the tx_queue.

Impact

Exploitation of this vulnerability leads to a memory leak, where allocated memory is not properly released, potentially causing increased memory usage and degradation of system performance over time.
