Its\narp_dev field may contain IFNAMSIZ bytes without a NUL terminator.\n\nSuch input is passed to dev_get_by_name_rcu() or __dev_get_by_name(), where\nstrcmp() can read past the end of the stack object when a matching\nalternative interface name exists.\n\nTerminate the field before the lookup to prevent the out-of-bounds read.","categories":["Operating
