Unlike major launches (e.g., 25.0), a patch version like 25.4.1 signals refinement. Typically, Adobe releases such updates to address critical bugs, security vulnerabilities, or macOS compatibility issues without introducing disruptive new features. For users on macOS Big Sur or Monterey, this version became a “golden build” due to its stability.
Adobe’s security bulletin APSB21-21 identified two critical vulnerabilities (CVE-2021-28545 and CVE-2021-28546) in versions prior to 25.4.1. These were memory corruption bugs that could lead to arbitrary code execution. Version 25.4.1 patches both.

Solution: Open Terminal (Applications > Utilities) and run:
