net: bridge: use DEV_STATS_INC()
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: use DEV_STATS_INC()
syzbot/KCSAN reported data-races in br_handle_frame_finish() [1]
This function can run from multiple cpus without mutual exclusion.
Adopt SMP safe DEV_STATS_INC() to update dev->stats fields.
Handles updates to dev->stats.tx_dropped while we are at it.
