Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.382.49

medium Tenable Cloud Security Plugin ID 451728

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: espintcp: remove encap socket caching
 to avoid reference leak The current scheme for caching the encap socket can lead to reference leaks when
 we try to delete the netns. The reference chain is: xfrm_state -> enacp_sk -> netns Since the encap socket
 is a userspace socket, it holds a reference on the netns. If we delete the espintcp state (through flush
 or individual delete) before removing the netns, the reference on the socket is dropped and the netns is
 correctly deleted. Otherwise, the netns may not be reachable anymore (if all processes within the ns have
 terminated), so we cannot delete the xfrm state to drop its reference on the socket. This patch results in
 a small (~2% in my tests) performance regression. A GC-type mechanism could be added for the socket cache,
 to clear references if the state hasn't been used "recently", but it's a lot more complex than just not
 caching the socket. (CVE-2025-38097)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.382.49 or later.
