The authors claim that the A2 system achieves 78.3 percent coverage on the Ghera benchmark, surpassing static analyzers like APKHunt (30.0 percent). And they say that, when they used A2 on 169 production APKs, they found "104 true-positive zero-day vulnerabilities," 57 of which were self-validated via automatically generated proof-of-concept (PoC) exploits. One of these included a medium-severity flaw in an Android app with over 10 million installs.
Patch Tuesday is next week, but Android is ahead of the game, dropping its biggest patch bundle this year while attackers actively exploit two of the now-fixed flaws. This month, the world's most popular mobile operating system pushed out 120 patches, its biggest monthly dump this year. It's a far cry from July, when Android didn't issue a single patch as everything was apparently fine, but in September, two of the flaws may be under "limited, targeted exploitation."
The vulnerabilities include CVE-2025-21479 (CVSS score: 8.6) and CVE-2025-27038 (CVSS score: 7.5), both of which were disclosed alongside CVE-2025-21480 (CVSS score: 8.6) by the chipmaker back in June 2025.
