CVE-2025-38199

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath12k: Fix memory leak due to multiple rx_stats allocation<br /> <br /> rx_stats for each arsta is allocated when adding a station.<br /> arsta-&gt;rx_stats will be freed when a station is removed.<br /> <br /> Redundant allocations are occurring when the same station is added<br /> multiple times. This causes ath12k_mac_station_add() to be called<br /> multiple times, and rx_stats is allocated each time. As a result there<br /> is memory leaks.<br /> <br /> Prevent multiple allocations of rx_stats when ath12k_mac_station_add()<br /> is called repeatedly by checking if rx_stats is already allocated<br /> before allocating again. Allocate arsta-&gt;rx_stats if arsta-&gt;rx_stats<br /> is NULL respectively.<br /> <br /> Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1<br /> Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
