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.

CVE-2026-23096 [MEDIUM] kernel: uacce: fix cdev handling in the cleanup path
kernel: uacce: fix cdev handling in the cleanup path
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.
