SyncGHSA-rr8g-9fpq-6wmg / RUSTSEC-2025-0023
More information
Details
The broadcast channel internally calls
cloneon the stored value when receiving it, and only requiresT:Send. This means that using the broadcast channel with values that areSendbut notSynccan trigger unsoundness if thecloneimplementation makes use of the value being!Sync.Thank you to Austin Bonander for finding and reporting this issue.

Release Notes

v1.38.2: Tokio v1.38.2Compare Source
This release fixes a soundness issue in the broadcast channel. The channel accepts values that are
Sendbut!Sync. Previously, the channel calledclone()on these values without synchronizing. This release fixes the channel by synchronizing calls to.clone()(Thanks Austin Bonander for finding and reporting the issue).Fixed
