high Tenable Cloud Security Plugin ID 470512

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: packet: use consistent hard_header_len
in TX_RING send path tpacket_snd() reads dev->hard_header_len independently for skb allocation and header
construction in tpacket_fill_skb(). Concurrent netdevice reconfiguration can therefore make the reserved
headroom smaller than the amount later pushed, or make copylen - hard_header_len negative. Snapshot
hard_header_len once before processing ring frames and use it for the frame limit, headroom allocation,
copy length, and skb construction. Pass the snapshot to tpacket_fill_skb(). The separate SOCK_DGRAM
consistency problem between hard_header_len and header_ops->create is not addressed here. (CVE-2026-74668)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.28 or later.
