Active exploitationNonot in the CISA catalog
Public exploitAvailablePublished on Exploit-DB

The Linux 2.2.x kernel does not restrict the number of Unix domain sockets as defined by the wmem_max parameter, which allows local users to cause a denial of service by requesting a large number of sockets.

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.
