CVE-2026-23096 Details
Description
In the Linux kernel, the following vulnerability has been resolved: uacce: fix cdev handling in the cleanup path When cdev_device_add fails, it internally releases the cdev memory, and if cdev_device_del is then executed, it will cause a hang error. To fix it, we check the return value of cdev_device_add() and clear uacce->cdev to avoid calling cdev_device_del in the uacce_remove.
A vulnerability exists in the Linux kernel's uacce driver related to the management of character device (cdev) resources. When the function cdev_device_add fails, it releases the associated cdev memory. If cdev_device_del is subsequently called, it can lead to a hang error. This issue arises because the cleanup process does not properly handle the failure case, creating a potential for resource management errors.
The vulnerability has been addressed by modifying the uacce_register function to check the return value of cdev_device_add. If the addition fails, the cdev pointer is cleared to prevent cdev_device_del from being called during the removal process.
