Details

In the Linux kernel, the following vulnerability has been resolved:

net: bridge: use DEVSTATSINC()

syzbot/KCSAN reported data-races in brhandleframe_finish() [1] This function can run from multiple cpus without mutual exclusion.

Adopt SMP safe DEVSTATSINC() to update dev->stats fields.

Handles updates to dev->stats.tx_dropped while we are at it.
