high Tenable Self-Hosted Container Security Plugin ID 465879

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: pppoe: drop PFC frames RFC 2516
 Section 7 states that Protocol Field Compression (PFC) is NOT RECOMMENDED for PPPoE. In practice, pppd
 does not support negotiating PFC for PPPoE sessions, and the current PPPoE driver assumes an uncompressed
 (2-byte) protocol field. However, the generic PPP layer function ppp_input() is not aware of the
 negotiation result, and still accepts PFC frames. If a peer with a broken implementation or an attacker
 sends a frame with a compressed (1-byte) protocol field, the subsequent PPP payload is shifted by one
 byte. This causes the network header to be 4-byte misaligned, which may trigger unaligned access
 exceptions on some architectures. To reduce the attack surface, drop PPPoE PFC frames. Introduce
 ppp_skb_is_compressed_proto() helper function to be used in both ppp_generic.c and pppoe.c to avoid open-
 coding. (CVE-2026-53003)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.77 or later.
