CVE-2025-12105 (GCVE-0-2025-12105)

Vulnerability from cvelistv5 – Published: 2025-10-23 09:14 – Updated: 2026-06-29 23:28

Title

Libsoup: heap use-after-free in libsoup message queue handling during http/2 read completion

Summary

A flaw was found in the asynchronous message queue handling of the libsoup library, widely used by GNOME and WebKit-based applications to manage HTTP/2 communications. When network operations are aborted at specific timing intervals, an internal message queue item may be freed twice due to missing state synchronization. This leads to a use-after-free memory access, potentially crashing the affected application. Attackers could exploit this behavior remotely by triggering specific HTTP/2 read and cancel sequences, resulting in a denial-of-service condition.

Severity
