In the Linux kernel, the following vulnerability has been resolved:
net: arp: terminate device name before lookup
The ARP ioctl copies a user-provided struct arpreq into a stack object. Its
arp_dev field may contain IFNAMSIZ bytes without a NUL terminator.
Such input is passed to dev_get_by_name_rcu() or __dev_get_by_name(), where
strcmp() can read past the end of the stack object when a matching
alternative interface name exists.
Terminate the field before the lookup to prevent the out-of-bounds read.
