What it is stated by the CNA
A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.

Outside the record researched, cited
This section reads the record's references and adds cited findings from outside it. It needs an account. Everything above is held facts and is complete without it.
What would change this brief held, dated
- CISA KEV
- Not listed in the catalogue we hold. A listing changes this brief.
- exploit probability
- 0.68 on 2026-10-05 (FIRST's EPSS, a probability and not evidence of exploitation). Next band line: 90% (0.90). Crossing a line changes this brief.
- fix
- Held: kernel 4.14.266; kernel 4.19.229; kernel 4.9.301; kernel 5.10.100; kernel 5.15.23; kernel 5.16.9. A newer fix from the CNA or OSV changes this brief.
How to check this
Every value above is held with two dates: when it was true upstream (as_of) and when we recorded it (tx_from). Re-derive the exploit probability as it stood on any date:
SELECT value, source, source_version, as_of, tx_from
FROM volatile_valid_as_of('CVE-2022-0435', '2026-10-31T23:59:59.999999Z', now());
