Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
net: hsr: remove WARN_ONCE() in send_hsr_supervision_frame()
Syzkaller reported [1] hitting a warning after failing to allocate resources for skb in hsr_init_skb(). Since a WARN_ONCE() call will not help much in this case, it might be prudent to switch to netdev_warn_once(). At the very least it will suppress syzkaller reports such as [1].
Just in case, use netdev_warn_once() in send_prp_supervision_frame() for similar reasons.
[1]
