Echo: linux: security update to 6.1.180-1

critical Tenable Cloud Security Plugin ID 458757

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 linux library and its related packages to version 6.1.180-1 or later.
