CVE-2023-46569Public exploitNetwork attack vector

Analysis crash via undersized mnemonic lookup table

Published Oct 28, 2023 · Updated Sep 9, 2024

Out-of-bounds read in radare2 5.8.9 and earlier allows attackers to crash binary analysis with a crafted NDS32 input. The print_insn32_fpu function uses decoded comparison-selector values to index an eight-entry mnemonic_fs2_cmp table that lacks entries for values 8 and 9. Triggering requires analysis of the supplied file; the public proof of concept demonstrates an AddressSanitizer abort rather than code execution.
