Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.582.86

medium Tenable Self-Hosted Container Security Plugin ID 451308

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlink_log: fix
 uninitialized padding leak in NFULA_PAYLOAD __build_packet_message() manually constructs the NFULA_PAYLOAD
 netlink attribute using skb_put() and skb_copy_bits(), bypassing the standard nla_reserve()/nla_put()
 helpers. While nla_total_size(data_len) bytes are allocated (including NLA alignment padding), only
 data_len bytes of actual packet data are copied. The trailing nla_padlen(data_len) bytes (1-3 when
 data_len is not 4-byte aligned) are never initialized, leaking stale heap contents to userspace via the
 NFLOG netlink socket. Replace the manual attribute construction with nla_reserve(), which handles the
 tailroom check, header setup, and padding zeroing via __nla_reserve(). The subsequent skb_copy_bits()
 fills in the payload data on top of the properly initialized attribute. (CVE-2026-31428)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.582.86 or later.
