medium Tenable Cloud Security Plugin ID 467121

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: xsk: validate MTU against usable frame
size on bind AF_XDP bind currently accepts zero-copy pool configurations without verifying that the device
MTU fits into the usable frame space provided by the UMEM chunk. This becomes a problem since we started
to respect tailroom which is subtracted from chunk_size (among with headroom). 2k chunk size might not
provide enough space for standard 1500 MTU, so let us catch such settings at bind time. Furthermore,
validate whether underlying HW will be able to satisfy configured MTU wrt XSK's frame size multiplied by
supported Rx buffer chain length (that is exposed via net_device::xdp_zc_max_segs). (CVE-2026-43092)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.381.132 or later.
