CWEhttps://cwe.mitre.org/data/definitions/416.html

Use-after-free vulnerability in the XML parser in Google Chrome before 18.0.1025.168 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
