medium Tenable Self-Hosted Container Security Plugin ID 469163

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: net: af_key: zero aligned sockaddr
tail in PF_KEY exports PF_KEY export paths use `pfkey_sockaddr_size()` when reserving sockaddr payload
space, so IPv6 addresses occupy 32 bytes on the wire. However, `pfkey_sockaddr_fill()` initializes only
the first 28 bytes of `struct sockaddr_in6`, leaving the final 4 aligned bytes uninitialized. Not every
PF_KEY message is affected. The state and policy dump builders already zero the whole message buffer
before filling the sockaddr payloads. Keep the fix to the export paths that still append aligned sockaddr
payloads with plain `skb_put()`: - `SADB_ACQUIRE` - `SADB_X_NAT_T_NEW_MAPPING` - `SADB_X_MIGRATE` Fix
those paths by clearing only the aligned sockaddr tail after `pfkey_sockaddr_fill()`. (CVE-2026-43088)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.395.47 or later.
