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: netfilter: nf_tables_offload: suppress
WARN_ON_ONCE for ENOMEM in abort path In nft_flow_rule_offload_abort(), WARN_ON_ONCE(err) is triggered on
every error during rollback, including -ENOMEM. Memory allocation failures are expected under low-memory
conditions and do not indicate a kernel bug. Trace for example: nft_flow_offload_chain() //
FLOW_BLOCK_BIND nft_flow_block_chain() nft_chain_offload_cmd() nft_block_offload_cmd() ->ndo_setup_tc()
nsim_setup_tc() flow_block_cb_setup_simple() flow_block_cb_alloc() // fails to -ENOMEM The warning was
reproduced on the 5.10 stable kernel under memory pressure via fault injection, but the underlying bug
exists in mainline as well, as demonstrated by the ENOMEM trace above. The following splat was triggered
during nf_tables transaction processing: WARNING: CPU: 0 PID: 8567 at

WARN_ON_ONCE(err && err != -ENOMEM) so that warnings are only emitted for unexpected errors. This aligns
with the common kernel practice of not warning on -ENOMEM. Found by Linux Verification Center
(linuxtesting.org) with Syzkaller. (CVE-2026-80744)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
