critical Tenable Self-Hosted Container Security Plugin ID 468832

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: esp: restore combined single-
 frag length gate The ESP out-of-place fast path appends the trailer in esp_output_head() before
 esp_output_tail() allocates the destination page frag. The head-side gate currently checks skb->data_len
 and tailen separately, but the tail code allocates a single destination frag from the combined post-
 trailer skb->data_len. Reject the page-frag fast path when the combined aligned length exceeds a page.
 Otherwise skb_page_frag_refill() may fall back to a single page while the destination sg still spans the
 combined skb->data_len. Restore this combined-length page gate for both IPv4 and IPv6. (CVE-2026-63912)

Solution

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