CVE-2022-49422 Details
Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix the error handling path in idxd_cdev_register() If a call to alloc_chrdev_region() fails, the already allocated resources are leaking. Add the needed error handling path to fix the leak.
A vulnerability in the Linux kernel's DMA engine component for Intel's Integrated Accelerator (IDXD) has been addressed. The issue was related to improper error handling in the function idxd_cdev_register(). When the function alloc_chrdev_region() failed, it caused a resource leak by not releasing already allocated resources. The vulnerability has been fixed by adding the necessary error handling to prevent this resource leak.
