Technical Analysis

This advisory covers several vulnerabilities in WebKitGTK+, including CVE-2025-43529 (use-after-free due to improper memory management) and multiple CVEs (CVE-2025-43501, CVE-2025-43531, CVE-2025-43535, CVE-2025-43536, CVE-2025-43541) where processing maliciously crafted web content may lead to unexpected process crashes.
