ethtool: coalesce: cap profile updates at NET_DIM_PARAMS_NUM_PROFILES

In the Linux kernel, the following vulnerability has been resolved:

ethtool: coalesce: cap profile updates at NET_DIM_PARAMS_NUM_PROFILES

ethnl_update_profile() walks the ETHTOOL_A_PROFILE_IRQ_MODERATION
nest list with an index 'i' and writes new_profile[i++] without
bounding i. The destination is kmemdup()'d at NET_DIM_PARAMS_NUM_PROFILES
entries (5), but the Netlink nest count is entirely user-controlled.
Netlink policies do not have support for constraining the number
of nested entries (or number of multi-attr entries).
Daten sind bereitgestellt durch das CVE Programm von einer CVE Numbering Authority (CNA) (Unstrukturiert).
