- Summary
- nvmet: fix refcount leak in nvmet_sq_create()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix refcount leak in nvmetsqcreate()
In nvmetsqcreate(), a reference on the ctrl is taken via krefgetunlesszero() before calling nvmetchecksqid(). If nvmetcheck_sqid() fails, the function returns the error directly without releasing the reference, leading to a leak.
Fix this by jumping to the "ctrlput" label, which already performs the necessary nvmetctrl_put(ctrl). This ensures the reference is properly released on this error path.
