medium Tenable Self-Hosted Container Security Plugin ID 451284

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: bridge: fix nd_tbl NULL
 dereference when IPv6 is disabled When booting with the 'ipv6.disable=1' parameter, the nd_tbl is never
 initialized because inet6_init() exits before ndisc_init() is called which initializes it. Then, if
 neigh_suppress is enabled and an ICMPv6 Neighbor Discovery packet reaches the bridge, br_do_suppress_nd()
 will dereference ipv6_stub->nd_tbl which is NULL, passing it to neigh_lookup(). This causes a kernel NULL
 pointer dereference. BUG: kernel NULL pointer dereference, address: 0000000000000268 Oops: 0000 [#1]
 PREEMPT SMP NOPTI [...] RIP: 0010:neigh_lookup+0x16/0xe0 [...] Call Trace: <IRQ> ? neigh_lookup+0x16/0xe0
 br_do_suppress_nd+0x160/0x290 [bridge] br_handle_frame_finish+0x500/0x620 [bridge]
 br_handle_frame+0x353/0x440 [bridge] __netif_receive_skb_core.constprop.0+0x298/0x1110

 net_rx_action+0x2c4/0x3a0 handle_softirqs+0xd0/0x270 do_softirq+0x3f/0x60 Fix this by replacing
 IS_ENABLED(IPV6) call with ipv6_mod_enabled() in the callers. This is in essence disabling NS/NA
 suppression when IPv6 is disabled. (CVE-2026-23381)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.582.62 or later.
