lnsfw1.sys 6.0.2900.5512 in Look 'n' Stop Firewall 2.06p4 and 2.07 allows local users to cause a denial of service (crash) via a crafted 0x80000064 IOCTL request that triggers an assertion failure. NOTE: some of these details are obtained from third party information.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:N/I:N/A:P
Base score: 2.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.75%
Percentile among all scored CVEs: 53
Score date: 10/9/2026

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.
