Can you explain this vulnerability to me?
This vulnerability is a memory leak in the Linux kernel's mt7615 driver. Specifically, in the function mt7615_mcu_wtbl_sta_add(), a memory buffer (skb sskb) is allocated, but if a subsequent function call (mt76_connac_mcu_alloc_wtbl_req()) fails, the allocated memory is not freed, causing a memory leak. The fix involves properly freeing the allocated memory in the error handling path.
How can this vulnerability impact me? :
The memory leak can lead to increased memory usage over time, potentially causing system instability or crashes if the leak is exploited or occurs frequently. This can degrade system performance and reliability.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, update the Linux kernel to a version that includes the fix for the memory leak in mt7615_mcu_wtbl_sta_add(). This fix ensures that the allocated skb (sskb) is properly freed in the error handling path, preventing memory leaks.
