In the Linux kernel, the following vulnerability has been resolved:
wireguard: receive: annotate data-race around receiving_counter.counter
Syzkaller with KCSAN identified a data-race issue when accessing keypair->receiving_counter.counter. Use READ_ONCE() and WRITE_ONCE() annotations to mark the data race as intentional.
