bonding: Fix out-of-bounds read in bond_option_arp_ip_targets_set()
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.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
