CVE-2026-23451
Description
A flaw was found in the Linux kernel's bonding component. When a specific network configuration involving a stack of two bonding devices is set up, the bond_header_parse() function can enter an infinite loop. This vulnerability can lead to a Denial of Service (DoS), making the affected system unresponsive.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
