Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: net/rds: Clear reconnect pending bit When canceling the reconnect worker, care must be taken to reset the reconnect-pending bit. If the reconnect worker has not yet been scheduled before it is canceled, the reconnect-pending bit will stay on forever.

In a critical RDS deployment this can fully deny communication to that peer, so high availability impact is appropriate."
