CVE-2024-41079  (opens in a new tab)

How to fix?

Upgrade SLES:15.5 kernel-docs to version 5.14.21-150500.55.80.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs package and not the kernel-docs package as distributed by SLES. See How to fix? for SLES:15.5 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.
