CVE-2023-54028

/// Technical description

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

RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task"

In the function rxe_create_qp(), rxe_qp_from_init() is called to

initialize qp, internally things like rxe_init_task are not setup until

rxe_qp_init_req().

If an error occurred before this point then the unwind will call

rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()

which will oops when trying to access the uninitialized spinlock.

If rxe_init_task is not executed, rxe_cleanup_task will not be called.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
