What is CVE-2025-7424?

A vulnerability exists in the libxslt library due to improper handling of memory fields during XML transformations, specifically through the simultaneous use of the psvi memory field for both stylesheet and input data. This situation may lead to type confusion, which can result in significant application instability, possibly allowing attackers to crash the application or corrupt its memory. When exploited, it may cause denial of service or trigger unpredictable behavior, posing a risk to the reliability and security of systems relying on this library.
