In the Linux kernel, the following vulnerability has been resolved:
afunix: Fix a data-race in unixdgrampeerwake_me().
unixdgrampoll() calls unixdgrampeerwakeme() without other
's
lock held and check if its receive queue is full. Here we need to
use unixrecvqfulllockless() instead of unixrecvq_full(), otherwise
KCSAN will report a data-race.
