Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue arises when too many RDMA resources are allocated, and the current timeout does not allow the rxe to handle these resources correctly, potentially leading to incorrect release of RDMA resources. This is notable compared to other RDMA drivers, which use a bigger timeout.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
