DescriptionNVD

A specific function code receives a raw pointer supplied by the user and deallocates this pointer. The user can then control what memory regions will be freed and cause use-after-free condition.

AnalysisAI

A specific function code receives a raw pointer supplied by the user and deallocates this pointer. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, low attack complexity. This Use After Free vulnerability could allow attackers to access freed memory to execute arbitrary code or crash the application.

Technical ContextAI

This vulnerability is classified as Use After Free (CWE-416), which allows attackers to access freed memory to execute arbitrary code or crash the application.
