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: udp_tunnel: fix NULL deref caused by
 udp_sock_create6 when CONFIG_IPV6=n When CONFIG_IPV6 is disabled, the udp_sock_create6() function returns
 0 (success) without actually creating a socket. Callers such as fou_create() then proceed to dereference
 the uninitialized socket pointer, resulting in a NULL pointer dereference. The captured NULL deref crash:
 BUG: kernel NULL pointer dereference, address: 0000000000000018 RIP: 0010:fou_nl_add_doit

 entry_SYSCALL_64_after_hwframe (net/arch/x86/entry/entry_64.S:130) This patch makes udp_sock_create6
 return -EPFNOSUPPORT instead, so callers correctly take their error paths. There is only one caller of the
 vulnerable function and only privileged users can trigger it. (CVE-2026-23439)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.534.80 or later.
