CERT-FR published an advisory describing a denial-of-service vulnerability affecting multiple Kaspersky product components, including the Network Agent module for Windows XP SP2/SP3 and later Windows versions, Kaspersky Next Expert View and Pro View Network Agent modules, and the Kaspersky Security Center Administration Server module. The flaw is tracked as CVE-2026-88941 and was disclosed via Kaspersky's own security bulletin (12430#291026) on 29 October 2026.
No details on exploitation in the wild are provided in the advisory, and no proof-of-concept or active exploitation is mentioned. The risk is limited to denial of service, meaning an attacker could disrupt availability of the affected management or agent components rather than achieve code execution or data compromise.
Defenders running affected Kaspersky versions should apply the vendor-supplied patches referenced in the official Kaspersky bulletin. Affected versions include Network Agent builds prior to 10.5.0.1781 (XP SP2), 14.0.0.20145 (XP SP3), and 17.0.0.3992 (Windows), Next Expert View Network Agent prior to 16.2.0.1547, Next Pro View Network Agent prior to 15.1.0.22268, and Security Center Administration Server prior to 15.1.0.28509 Update 3.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
