+# Hardware-assisted AddressSanitizer
+
+```{contents}
+:local: true
+```
+
+## Introduction
+
+Hardware-assisted AddressSanitizer (HWASan) is a memory error detector similar
+to {doc}`AddressSanitizer`, but based on memory tagging and address tagging
+(such as Top-Byte Ignore on AArch64). It provides similar bug detection with
+significantly lower memory overhead (~10–20%).
+
+HWASan can detect:
+
+- Out-of-bounds accesses (heap, stack, and globals)
+- Use-after-free
+- Use-after-return and use-after-scope
+- Double-free and invalid free
+
+## Supported Platforms
+
+- **Linux AArch64** (kernel 5.4+ with tagged address ABI)
+- **Android AArch64**
+- **Linux RISC-V 64**
+- **Linux x86_64** (experimental)
