CVE-2022-49813 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: ena: Fix error handling in ena_init() The ena_init() won't destroy workqueue created by create_singlethread_workqueue() when pci_register_driver() failed. Call destroy_workqueue() when pci_register_driver() failed to prevent the resource leak.
A vulnerability in the Linux kernel's ENA (Elastic Network Adapter) driver was introduced by improper error handling in the ena_init() function. When pci_register_driver() failed, the function did not properly destroy the workqueue created by create_singlethread_workqueue(), leading to a resource leak. The vulnerability has been addressed by modifying the error handling to ensure that the workqueue is destroyed if pci_register_driver() fails.
