 - 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). (CVE-2026-63987)
