How to fix?

Upgrade Oracle:9 bpftool to version 0:7.4.0-503.11.1.el9_5 or higher.
This issue was patched in ELSA-2024-9315.

NVD Description

Note: Versions mentioned in the description apply only to the upstream bpftool package and not the bpftool package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

nvmet: always initialize cqe.result

The spec doesn't mandate that the first two double words (aka results) for the command queue entry need to be set to 0 when they are not used (not specified). Though, the target implemention returns 0 for TCP and FC but not for RDMA.

Let's make RDMA behave the same and thus explicitly initializing the result field. This prevents leaking any data from the stack.
