Details

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->receivingcounter.counter. Use READONCE() and WRITE_ONCE() annotations to mark the data race as intentional.

BUG: KCSAN: data-race in wg_packet_decrypt_worker / wg_packet_rx_poll
