Description Sandipan Roy 2022-11-17 04:39:27 UTC 
An issue was discovered in the tokio crate before 1.8.4, and 1.9.x through 1.13.x before 1.13.1, for Rust. In certain circumstances involving a closed oneshot channel, there is a data race and memory corruption.

Hi Sandipan,

None of the aardvark/netavark is using `oneshot` directly but our deps could be using it but our tokio version is `1.21.2` which newer than the versions listed above. So I think `netavark` and `aardvark` are not affected by this.

Thanks
Aditya
