Kernel Address Sanitizer Comes To LLVM's Clang

Written by Michael Larabel in LLVM on 19 June 2015 at 09:43 AM EDT. 2 Comments

LLVM's Clang C/C++ compiler now has initial Kernel Address Sanitizer support.

The Kernel Address Sanitizer is Google's AddressSanitizer (ASan) fast memory error detector modified for the Linux kernel. ASan finds use-after-frees, heap/stack/global buffer overflow bugs, and other memory issues within C and C++ code-bases. Clang has already supported ASan but now it has support for the Linux kernel ASan.

With this commit to LLVM and this to Clang, -fsanitize=kernel-address can be passed to Clang for utilizing the KASan.

Those wishing to learn more about Address Sanitizer for Clang or GCC, visit the Google Code site.
