Use After Free
The Chrome Web Store inline-installation implementation in the Extensions subsystem in Google Chrome before 52.0.2743.82 does not properly consider object lifetimes during progress observation, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted web site.
CWE-416 - Use After Free
Use-after-free (UaF) vulnerability occurs when the application is using a pointer to memory that has been freed. Any attempt to read/write to a buffer after it is de-allocated allows memory corruption, sensitive information exposure, and can potentially lead to arbitrary code execution.
