Vulnerability from gsd
Modified
2024-02-20 06:02
Details
In the Linux kernel, the following vulnerability has been resolved:
packet: annotate data-races around ignore_outgoing
ignore_outgoing is read locklessly from dev_queue_xmit_nit()
and packet_getsockopt()
Add appropriate READ_ONCE()/WRITE_ONCE() annotations.
syzbot reported:
