CVE-2025-46420

Summary

CVE-2025-46420 is a newly identified vulnerability affecting the libsoup library. This issue arises from a memory leak in the soup_header_parse_quality_list() function, which is responsible for parsing Quality lists. When encountering a Quality list containing only elements with all zeroes, this function fails to properly manage memory resources, leading to a memory leak. This can potentially be exploited by attackers to consume large amounts of memory, resulting in denial-of-service (DoS) conditions or other unwanted side effects. System administrators are advised to update their installations of libsoup as soon as possible to mitigate this risk.
