Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition exists in the ibmpex driver. The issue occurs because driver data is set to NULL before sensor attributes are removed. The function
ibmpex show sensor() retrieves this driver data via dev get drvdata() but fails to check if the value is NULL before dereferencing it to access data->sensors[]. If a userspace process reads a sensor file while the delete function is executing, it can trigger a crash in ibmpex show sensor().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
