In the Linux kernel, the following vulnerability has been resolved: bonding: Fix out-of-bounds read in bond_option_arp_ip_targets_set() In function bond_option_arp_ip_targets_set(), if newval->string is an empty string, newval->string+1 will point to the byte after the string, causing an out-of-bound read.
