Questions about CVE-2026-75882
What does this mean?
A privileged kernel driver in these ESET products can be made to carry out requests on an attacker's behalf under SYSTEM privileges. The advisory describes possible unauthorized disclosure of sensitive disk metadata, coerced authentication to remote systems, or loss of access to the encrypted volume.Source: support.eset.com
Am I affected, and how do I check?
Systems with ESET Endpoint Encryption 5.4.23.0 or earlier for Windows, or ESET Full Disk Encryption 2.4.4.0 or earlier for Windows, installed. To check, look up the installed version of the ESET product on the system.Source: support.eset.com
What should I do about it?
Upgrade ESET Endpoint Encryption to 5.4.29.0 or later for Windows. The checked facts list no fixed version for ESET Full Disk Encryption.Source: support.eset.com
Is it being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
