UBUNTU-CVE-2026-97491: Medium severity ubuntu/linux vulnerability
In the Linux kernel, the following vulnerability has been resolved: net/rds: Don't sleep inside rdsibconnpathshutdown New rds rdma self tests exposed a hang when tearing down the ib network configs. This is caused by the shutdown worker thread sleeping on the waitevent call, which blocks other work items in the queue. Fix this by changing waitevent to waitevent timeout, and looping until the wait check succeeds.
