Efficiently Rebuilding Coverage in Hardware-Assisted Greybox Fuzzing

Coverage-based greybox fuzzing (CGF) is an efficient technique for detecting vulnerabilities, but its coverage-feedback mechanism introduces significant overhead in binary-only fuzzing. Although hardware-assisted greybox fuzzing (HGF) has been proposed to address this issue, existing approaches struggle to achieve a balance between the efficiency and sensitivity of coverage, as well as to cope with trace buffer overflow.
