## What to check

- Applies to: The 1 CVE named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

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.
