Linux Kernel Security Vulnerabilities
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...
