When an ARM64 application crashes with SIGILL after executing an SVE instruction, the problem can lie in the CPU, kernel, or build flags. This guide walks through a quick diagnostics table, ordered checks, fixes, and when to seek escalation.
Decide whether to use ARM64 Large System Extensions (LDAXR/STXR) or traditional LDREX/STREX for lock‑free data structures. Compare CPU, OS, compiler support, performance, and pitfalls, and see a practical C example with runtime guard.
Learn how to use ARM64 Memory Tagging Extension (MTE) to detect heap buffer overflows and use-after-free errors with hardware-accelerated precision.
Learn how to implement ARM64 Pointer Authentication (PAC) to mitigate ROP attacks by signing return addresses using GCC/Clang and ARMv8.3-A hardware.
Learn how ARM64's Memory Tagging Extension (MTE) turns hardware tags into immediate exceptions for out‑of‑bounds accesses, and how to enable and verify it in Linux.
Step‑by‑step guide to diagnose ARM64 Pointer Authentication faults: check SCTLR_EL1, read PAC keys, inspect ESR/FAR, verify with a test program, and apply the appropriate fix.
A diagnostic guide for resolving ARMv8.5 Memory Tagging Extension (MTE) tag-check faults on AArch64, covering ESR analysis, pointer tag loss, and silicon errata.
Learn how ARMv8.3‑A Pointer Authentication (PAC) signs pointers to stop return‑oriented programming attacks, how to enable it with compiler flags, and how to verify support on your hardware.
A diagnostic guide for resolving ARM64 Memory Tagging Extension (MTE) faults, covering hardware verification, kernel configuration, and compiler alignment requirements.
