Last modified

CVE-2026-7164 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.43% chance of exploitation in the next 30 days.

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.
