| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw was discovered in the Linux kernel’s RDMA/mlx5 subsystem. Previously, when destroying a Queue Pair (QP) or Receive Queue (RQ), the firmware destruction result was ignored, and upper layers were not informed of failures. This could lead to issues, including kernel warnings, as upper layers continued operations assuming successful destruction when it had actually failed. The issue is now resolved by returning the correct firmware destruction status to upper layers, enabling proper handling of destruction failures for both RQs and QPs.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
