- wifi: ath12k: Fix memory leak due to multiple rx_stats allocation
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Fix memory leak due to multiple rx_stats allocation
rxstats for each arsta is allocated when adding a station. arsta->rxstats will be freed when a station is removed.
Redundant allocations are occurring when the same station is added multiple times. This causes ath12kmacstationadd() to be called multiple times, and rxstats is allocated each time. As a result there is memory leaks.
Prevent multiple allocations of rxstats when ath12kmacstationadd() is called repeatedly by checking if rxstats is already allocated before allocating again. Allocate arsta->rxstats if arsta->rx_stats is NULL respectively.
