CVE-2025-48431
Description
A flaw was found in Apache Thrift c_glib language bindings. A remote attacker could send specially crafted requests to a c_glib-based Thrift server, leading to a mismatched memory management routines vulnerability. This could cause the server to crash with a "free(): invalid pointer" error, resulting in a Denial of Service (DoS).
Statement
This is an Important denial of service vulnerability affecting Apache Thrift c_glib language bindings. Remote attackers can exploit this flaw by sending specially crafted requests to a c_glib-based Thrift server, leading to a server crash and service disruption. This impact is considered Important due to the potential for unauthenticated remote denial of service in Red Hat products that deploy and expose such Thrift servers.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
