Use-After-Free Vulnerability in Safari by Apple

CVE-2025-43368

What is CVE-2025-43368?

CVE-2025-43368 is a use-after-free vulnerability identified in the Safari web browser developed by Apple. This type of vulnerability arises when a program continues to use a pointer after the memory it points to has been freed, potentially leading to undefined behavior, system crashes, or exploitation opportunities. The vulnerability could negatively impact organizations by causing instability in the Safari browser, leading to unexpected crashes when processing maliciously crafted web content. Such crashes not only disrupt user activities but could also be leveraged by threat actors to perform further attacks, either by inducing denial-of-service conditions or by executing arbitrary code. The issue arises from inadequate memory management practices within the browser, underscoring the importance of robust coding standards in safeguarding user environments.
