CVE-2025-39695 Details
Description
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.
A vulnerability in the Linux kernel's RDMA/rxe component has been addressed. This issue involved improper management of RXE resources, such as Queue Pairs (QPs) and socket references, which could lead to call traces when certain packets were destroyed. To mitigate this, a timestamp is now added to socket buffer (skb) packets upon creation. This allows network devices to release delayed skb packets and free associated RXE resources if the packets have been held too long.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
