The netlink subsystem in the Linux kernel 2.4.x before 2.4.37.6 and 2.6.x before 2.6.13-rc1 does not initialize certain padding fields in structures, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors, related to the (1) tc_fill_qdisc, (2) tcf_fill_node, (3) neightbl_fill_info, (4) neightbl_fill_param_info, (5) neigh_fill_info, (6) rtnetlink_fill_ifinfo, (7) rtnetlink_fill_iwinfo, (8) vif_delete, (9) ipmr_destroy_unres, (10) ipmr_cache_alloc_unres, (11) ipmr_cache_resolve, (12) inet6_fill_ifinfo, (13) tca_get_fill, (14) tca_action_flush, (15) tcf_add_notify, (16) tc_dump_action, (17) cbq_dump_police, (18) __nlmsg_put, (19) __rta_fill, (20) __rta_reserve, (21) inet6_fill_prefix, (22) rsvp_dump, and (23) cbq_dump_ovl functions.

Security readout for executives and security teams

This old Linux kernel flaw could let a local user read small amounts of unintended kernel memory through netlink responses. It matters mainly for legacy systems or appliances running very old or vendor-backported kernels, especially shared hosts where untrusted local users exist. Exposure is most likely on obsolete Linux 2.4 or early 2.6 kernels, embedded systems, legacy appliances, or unsupported distributions. Modern supported Linux distributions are unlikely to be affected unless running unusually old kernels without vendor backports. Treat this as a legacy exposure cleanup item, not an internet-wide emergency. Escalate only where old Linux kernels still host sensitive workloads or allow untrusted local users. Mitigation focus: Inventory systems for Linux 2.4.x and early 2.6.x kernels.; Apply vendor kernel updates containing the 2.4.37.6 or 2.6.13-rc1 fixes/backports.; Check Red Hat and SUSE advisories for distribution-specific corrected packages..
