CVE-2025-8197

NameCVE-2025-8197
DescriptionA global buffer overflow vulnerability was found in the soup_header_name_to_string function in Libsoup. The `soup_header_name_to_string` function does not validate the `name` parameter passed in, and directly accesses `soup_header_name_strings[name]`. The value of `name` is controllable, when `name` exceeds the index range of `soup_headr_name_string`, it will cause an out-of-bounds access.
