Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.0-rc2-00005-g307c1086d7c9

Description The Linux kernel contains an issue in cdev device add() related to error handling. Specifically, if device add() is injected with a fault and returns an error, and dev->devt is not set, cdev add() is not called, and cdev del() is unnecessarily attempted. This can lead to a null pointer dereference. The issue occurs during fault injection testing.

Recommendations Update to Linux kernel version 6.1.0-rc2-00005-g307c1086d7c9 or a later version to resolve this issue.
