CVE-2025-62496

The CVE refers to QuickJS: BigInt parsing in js_bigint_from_string. When converting a decimal string with an extremely large number of digits, the code computes n_bits as (n_digits × 27 + 7) / 8. For very large inputs (e.g., tens of millions of digits), this intermediate value overflows a 32-bit ...

CVE-2025-62495

CVE-2025-62495 describes an integer overflow in QuickJS regExp (libregexp). The DynBuf storing regex bytecode uses size_t, but several internal routines cast the DynBuf size_t to a signed int, so very large/complex patterns can exceed 2^31 bytes. The result is a negative value used for offsets (e...
