high Tenable Cloud Security Plugin ID 469458

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: xfrm: hold dev ref until after
 transport_finish NF_HOOK After async crypto completes, xfrm_input_resume() calls dev_put() immediately on
 re-entry before the skb reaches transport_finish. The skb->dev pointer is then used inside NF_HOOK and its
 okfn, which can race with device teardown. Remove the dev_put from the async resumption entry and instead
 drop the reference after the NF_HOOK call in transport_finish, using a saved device pointer since NF_HOOK
 may consume the skb. This covers NF_DROP, NF_QUEUE and NF_STOLEN paths that skip the okfn. For non-
 transport exits (decaps, gro, drop) and secondary async return points, release the reference inline when
 async is set. (CVE-2026-31663)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.3 or later.
