Does this matter?

Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.

Description

The tokio-boring library in version 4.0.0 is affected by a memory leak issue that can lead to excessive resource consumption and potential DoS by resource exhaustion. The set_ex_data function used by the library did not deallocate memory used by pre-existing data in memory each time after completing a TLS connection causing the program to consume more resources with each new connection.
