Vulnerability from github – Published: 2025-04-14 21:32 – Updated: 2025-04-14 21:32

Details

In the Linux kernel, the following vulnerability has been resolved:

coresight: syscfg: Fix memleak on registration failure in cscfg_create_device

device_register() calls device_initialize(), according to doc of device_initialize:

Use put_device() to give up your reference instead of freeing
* @dev directly once you have called this function.

To prevent potential memleak, use put_device() for error handling.

Severity

5.5 (Medium)
