Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the uninitialized payload of NLMSGDONE in the nfnetlinklog, leading to a leak of kernel heap data...

CVE-2026-31428

CVE-2026-31428 — In the Linux kernel, nfnetlink_log’s __build_packet_message() previously built NFULA_PAYLOAD attributes manually via skb_put()/skb_copy_bits(), bypassing nla_reserve()/nla_put(). This caused trailing padding to remain uninitialized, leaking stale heap data to userspace over NFLOG...

CVE-2026-31416

CVE-2026-31416 (Linux kernel) : Affected component is netfilter nfnetlink_log. The issue is caused by not accounting for the netlink header size when processing NL messages, which can lead to a WARN splat and potential drop of the affected netlink message, with no other ill effects reported in th...

This can lead to...

kernel: nfnetlink race in NETLINK_NFLOG socket creation

A race-condition flaw was discovered in the kernel's netlink module creation, which can trigger a kernel panic in netlinkrelease-moduleput for local users creating netlink sockets. The flaw is specific to Red Hat Enterprise Linux and does not affect upstream kernels. The nfnetlinklog module must ...
