Summary
Little Snitch version 3.0 through 3.6.1 suffer from a buffer overflow vulnerability that could be locally exploited which could lead to an escalation of privileges (EoP) and unauthorised ring0 access to the operating system. The buffer overflow is related to insufficient checking of parameters to the "OSMalloc" and "copyin" kernel API calls.
Exploit prediction
0.42% chance of exploitation in the next 30 days, higher than 36% of all scored CVEs (FIRST EPSS, 2026-11-09).
