Public exploitAvailablePublished on Exploit-DB

Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that leverages an improperly managed reference counter.

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.
