Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Fix memory leak due to multiple rx_stats allocation
rx_stats for each arsta is allocated when adding a station.
arsta->rx_stats will be freed when a station is removed.
Redundant allocations are occurring when the same station is added
multiple times. This causes ath12k_mac_station_add() to be called
multiple times, and rx_stats is allocated each time. As a result there
is memory leaks.
Prevent multiple allocations of rx_stats when ath12k_mac_station_add()
is called repeatedly by checking if rx_stats is already allocated
before allocating again. Allocate arsta->rx_stats if arsta->rx_stats
is NULL respectively.
