Description

This security bulletin contains information about 1 vulnerability.


1) Incorrect behavior order (CVE-ID: CVE-2026-90062)

CWE-ID: CWE-696 - Incorrect Behavior Order

CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause an inconsistent state between hardware-offloaded and software rulesets.

The vulnerability exists due to incorrect behavior order in nf_tables commit processing when committing rulesets with hardware flow-rule offload. A local user can commit a ruleset with hardware flow-rule offload to cause an inconsistent state between hardware-offloaded and software rulesets.

The inconsistency can occur if chain blob preparation fails after the hardware ruleset has been offloaded.
