critical Tenable Self-Hosted Container Security Plugin ID 466311

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: bpf: Reject fragmented frames in
devmap Devmap broadcast redirects clone the packet for all but the last destination. For native XDP, that
clone path copies only the linear xdp_frame data, while fragmented frames keep skb_shared_info in tailroom
outside the linear area. Cloning such a frame leaves XDP_FLAGS_HAS_FRAGS set but without valid frag
metadata, and the later free path can interpret uninitialized tail data as skb_shared_info, leading to an
out-of-bounds access during frame return. Reject fragmented native XDP frames in dev_map_enqueue_clone().
Add the same restriction to the generic XDP clone path in dev_map_redirect_clone(). Generic XDP represents
fragmented packets as nonlinear skbs, and rejecting them here keeps clone-based broadcast support aligned
between native and generic XDP. (CVE-2026-64355)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.37 or later.
