What is CVE-2025-7425?

A memory management flaw in libxslt allows improper handling of the atype attribute flags, leading to potential memory corruption. When the key() function in XSLT processes certain tree fragments, it fails to clean up ID attributes properly, which may result in the system accessing freed memory. This could cause application crashes or may be exploited by attackers to trigger heap corruption, posing significant risks to application stability and security.
