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

Description The start task() function in the Linux kernel may experience a null pointer dereference. This occurs because the return value of create singlethread workqueue() is not checked, potentially resulting in a NULL pointer being passed to subsequent functions, specifically leading to an access of wq->flags when wq is NULL.

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