Active exploitationNonot in the CISA catalog
Public exploitAvailablePublished on Exploit-DB
net/ipv4/af_inet.c in Linux kernel 2.4 does not clear sockaddr_in.sin_zero before returning IPv4 socket names from the (1) getsockname, (2) getpeername, and (3) accept functions, which allows local users to obtain portions of potentially sensitive memory.

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.
