In the Linux kernel, the following vulnerability has been resolved: net: nexthop: Initialize all fields in dumped nexthops struct nexthopgrp contains two reserved fields that are not initialized by nlaputnhgroup, and carry garbage. This can be observed e.g. with strace edited for clarity: ip...

CVE-2024-42272

CVE-2024-42272 affects the Linux kernel scheduling path: the act_ct patch fixes padding in zones_ht_key to avoid uninitialized padding being used by rhashtable lookups. The issue traces to a design change that enlarged the key from 2 to 16 bytes due to a struct net pointer, and the fix ensures rh...
