8.1 CVE-2024-53427
decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as numeric, which has a resultant stack-based buffer overflow and out-of-bounds write, as demonstrated by use of --slurp with subtraction, such as a filter of .-. when the input has a certain form of digit string with NaN (e.g., "1 NaN123" immediately followed by many more digits).

CWE-843 : Access of Resource Using Incompatible Type ('Type Confusion')
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type. Type confusion in CSS sequence leads to out-of-bounds read. Size inconsistency allows code execution, first discovered when it was actively exploited in-the-wild. Improperly-parsed file containing records of different types leads to code execution when a memory location is interpreted as a different object than intended.
