Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Buffer Overflow: Inadequate boundary validation in FastMemory during trace execution allows arbitrary memory corruption, presenting a severe risk during high-performance assembly execution.
Out of Bounds Write: A critical failure to validate target memory addresses against CKB_VM_ASM_RISCV_MAX_MEMORY in the RISC-V assembly interpreter allows out-of-bounds writes via memory-access instructions.
Memory Safety: Register corruption within the AMO (Atomic Memory Operation) CHECK_WRITE macro on x86_64 backends bypassed bounds checks due to temporary register clobbering, causing out-of-bounds access.
