Use after free in Portals in Google Chrome prior to 100.0.4896.60 allowed a remote attacker who convinced a user to engage in specific user interaction to potentially exploit heap corruption via user interaction.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
