Detailsinfo

A vulnerability was found in Linux Kernel up to 5.19.1 and classified as problematic. Affected by this issue is the function rxe_create_qp of the component RDMA. The manipulation with an unknown input leads to a initialization vulnerability. Using CWE to declare the problem leads to CWE-665. The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix error unwind in rxe_create_qp() In the function rxe_create_qp(), rxe_qp_from_init() is called to initialize qp, internally things like the spin locks are not setup until rxe_qp_init_req(). If an error occures 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. Move the spinlock initializations earlier before any failures.
