NVD Description

Note: Versions mentioned in the description apply only to the upstream mattermost-11.1 package and not the mattermost-11.1 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

The compiler is meant to unwrap pointers which are the operands of a memory move; a no-op interface conversion prevented the compiler from making the correct determination about non-overlapping moves, potentially leading to memory corruption at runtime.
