Dataset Card for Dataset Name
SecVulEval is a collection of real-world C/C++ vulnerabilities.
Dataset Details
Dataset Description
The dataset is curated by collecting C/C++ vulnerability from NVD. It features statement-level vulnerable information, context information for vulnerable functions
(is_vulnerable=True), and other metadata such as CVE, CWE, commit information. The dataset contains vulnerable and non-vulnerable function samples.
Dataset Sources
The vulnerabilities (CVEs) are collected from NVD (https://nvd.nist.gov). Then, the corresponding patches to the vulnerabilities are collected from their respective git repositories.
Uses
The dataset comprises both vulnerable (43.23%) and non-vulnerable (56.77%) functions, with a total collection of 25,440 function. This large collection of functions make it suitable for training vulnerability detection model. The statement-level info, along with contextual information can make context-aware detection at finer-grained level possible. The dataset can also be used to evaluate C/C++ vulnerability detection models.
Dataset Structure
The dataset has 15 different fields.
- The
project_urlcolumn has 735 different values while theprojectcolumn has 707 unique values. This is because forproject == "Android", there are multiple different repositories. - The
changed_linesandchanged_statementscolumns include the changes in made in the patch as a list of (line, code) pair. Vulnerable functions include the deleted lines/statements and the non-vulnerable functions has the added lines/statements. - Some functions/vulnerabilities can be assigned to more than one CVE/CWE which is why
cve_listandcwe_listare given as lists, although in most cases there would be only one CVE and CWE id. - The
fixed_func_idincludes theidxnumber (first field in the dataset) of the corresponding fixed patch of a vulnerable function. This helps to easily pair the vulnerable functions with their fixing code. For non-vulnerable code it doesn't make sense for a "fixed" version and thefixed_func_idis just itself. - The
contextfield includes contextual information for vulnerable functions according to the five categories as discussed in the paper. It is added as the list of symbols and an explanation as generated by the LLM.
Other fields are self-explanatory.
