Public exploitAvailablePublished on Exploit-DB

Cisco IOS 11.2.x and 12.0.x does not limit the size of its redirect table, which allows remote attackers to cause a denial of service (memory consumption) via spoofed ICMP redirect packets to the router.

CVSS

Base score: 7.8
Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 9.56 %
Percentile among all scored CVEs: 95
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
