CVE-2006-6173

Status: ModifiedHigh (7.2)—💥 Exploit

Buffer overflow in the shared_region_make_private_np function in vm/vm_unix.c in Mac OS X 10.4.6 and earlier allows local users to execute arbitrary code via (1) a small range count, which causes insufficient memory allocation, or (2) a large number of ranges in the shared_region_make_private_np_args parameter.

CVSS

Exploitation probability (EPSS)

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.
