high Tenable Cloud Security Plugin ID 467038

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: ipv6: fix use-after-free in
 ip6_finish_output2() ip6_finish_output2() caches a pointer to the IPv6 destination address (daddr) before
 invoking lwtunnel_xmit(). The LWT-BPF transmit path or other encapsulation operations within
 lwtunnel_xmit() can reallocate the skb head, freeing the memory that daddr points to. When lwtunnel_xmit()
 returns LWTUNNEL_XMIT_CONTINUE, the function continues to use the stale daddr pointer to compute the
 nexthop and to look up or create the neighbour entry. This results in a use-after-free read, which can
 leak sensitive kernel data, pollute the neighbour table with arbitrary values, misdirect traffic, or crash
 the system. Fix this by re-fetching the IPv6 header and the destination address pointer after
 lwtunnel_xmit() returns LWTUNNEL_XMIT_CONTINUE, ensuring that the subsequent nexthop computation and
 neighbour lookup operate on valid memory. (CVE-2026-80792)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.584.23 or later.
