Acronis DeviceLock DLP: Write-what-where Condition
CVE-2026-41952 is a high-severity write-what-where condition vulnerability in Acronis DeviceLock DLP from Acronis, with a CVSS 3.0 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 9.0.93212 as the first without the flaw, so updating Acronis DeviceLock DLP to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.11% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

- Use OS-level preventative functionality integrated after the fact. Not a complete solution.
