CVE-2026-7164: pf can overflow the stack parsing crafted SCTP packets
- Severity: high (CVSS 7.5 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-04-30 · updated 2026-06-17
- Weakness: CWE-674
Description
Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can eventually result in a stack overflow and panic. Remote attackers can craft packets which cause affected systems to panic. This affects any system where pf is configured to process traffic, independent of the configured ruleset.
Affected products
- FreeBSD: 13.5, 13.5-beta3, 13.5-p1, 13.5-p10, 13.5-p11, 13.5-p12 (+31)
