Google Revealed Kernel Address Sanitizer To Harden Android Firmware
Android devices are popular among hackers due to the platform’s extensive acceptance and open-source nature.
However, it has a big attack surface with over 2.5 billion active Android devices all over the world.
It also poses challenges when it comes to prompt vulnerability patching due to its fragmented ecosystem that consists of different hardware vendors and delayed software updates.
Malware distribution, surveillance, and unauthorized financial gain, or any other malicious purpose are some examples of how cybercriminals take advantage of these loopholes in security.
Recently, Google unveiled the Kernel Address Sanitizer (KASan) to strengthen the Android firmware and beyond.
Android Firmware And Beyond
KASan (Kernel Address Sanitizer) has broad applicability across firmware targets. Incorporating KASan-enabled builds into testing and fuzzing can proactively identify memory corruption vulnerabilities and stability issues before deployment on user devices.

Google has already leveraged KASan on firmware targets, leading to the discovery and remediation of over 40 memory safety bugs, some critically severe, through proactive vulnerability detection.
Address Sanitizer (ASan) is a compiler instrumentation tool that identifies invalid memory access bugs like out-of-bounds, use-after-free, and double-free errors during runtime.
For user-space targets, enabling ASan is…
