In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Flush delayed SKBs while releasing RXE resources When skb packets are sent out, these skb packets still depends on the rxe resources, for example, QP, sk, when these packets are destroyed. If these rxe resources are released when the skb packets are destroyed, the call traces will appear. To avoid skb packets hang too long time in some network devices, a timestamp is added when these skb packets are created. If these skb packets hang too long time in network devices, these network devices can free these skb packets to release rxe resources.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.
