CVE-2022-50172:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2022-50172 affects the Linux kernel and involves a potential memory leak in the mt76x02u driver. The vulnerability was discovered in the __mt76x02u_mcu_send_msg routine where the socket buffer (skb) is not properly freed when mt76u_bulk_msg fails (NVD, Wiz).
Technical details
The vulnerability exists in the mt76 wireless driver subsystem of the Linux kernel, specifically in the mt76x02u component. The issue occurs in the __mt76x02u_mcu_send_msg function where there is a failure to free the socket buffer (skb) when mt76u_bulk_msg fails, which can result in memory leaks (NVD, Wiz).
Impact
The vulnerability could result in memory leaks in the Linux kernel when using the affected mt76x02u wireless driver. This could potentially lead to system resource exhaustion over time (Wiz).
Mitigation and workarounds
The vulnerability has been resolved by implementing a fix that ensures the skb is properly freed if mt76u_bulk_msg fails in the __mt76x02u_mcu_send_msg routine (NVD).
