CVE-2025-13032 is a critical privilege escalation vulnerability affecting Avast and AVG Antivirus for Windows prior to version 25.3. The flaw is described as a double-fetch issue in the sandbox kernel driver that can lead to a pool overflow. The available information indicates the bug arises from a time-of-check/time-of-use race condition in kernel-mode handling of attacker-controlled data, resulting in memory corruption in the driver. Successful exploitation allows an attacker to leverage the pool overflow to elevate privileges on the affected Windows system.
