high Tenable Cloud Security Plugin ID 467091

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: apparmor: mediate the implicit connect
 of TCP fast open sendmsg sendmsg()/sendto() with MSG_FASTOPEN is a combination of connect(2) and write(2):
 it opens the connection in the SYN. apparmor_socket_sendmsg() only checks AA_MAY_SEND, so a profile that
 grants send but denies connect lets a confined task open an outbound TCP/MPTCP connection that connect(2)
 would have refused, bypassing connect mediation. Mediate the implicit connect when MSG_FASTOPEN is set and
 a destination is supplied. Add it to apparmor_socket_sendmsg() (not the shared aa_sock_msg_perm() helper,
 which recvmsg also uses) and call aa_sk_perm() directly, mirroring the selinux and tomoyo fixes.
 sk_is_tcp() does not cover MPTCP fast open, so the SOCK_STREAM/IPPROTO_MPTCP arm is explicit.
 (CVE-2026-63828)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.28 or later.
