CVE-2013-4348
Status: ModifiedHigh (7.1)—💥 PoC
The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation.
CVSS
- Version: 2.0
- Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C
- Base score: 7.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 9.41%
- Percentile among all scored CVEs: 95
- Score date: 10/13/2026
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.
