CVE-2024-38633

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue arises when the last MAX3100 device is removed, triggering the removal of the driver. However, the code fails to update the respective global variable, leading to a kernel crash after an insmod — rmmod — insmod cycle. This results in a NULL pointer dereference. The error path in the probe is also affected by the variable not being cleared. To resolve this, the assignment should be moved after the successful uart register driver() call.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
