NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_55_133-default package and not the kernel-livepatch-5_14_21-150500_55_133-default package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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

s390/vfio-ap: fix memory leak in vfio_ap device driver

The device release callback function invoked to release the matrix device uses the dev_get_drvdata(device *dev) function to retrieve the pointer to the vfio_matrix_dev object in order to free its storage. The problem is, this object is not stored as drvdata with the device; since the kfree function will accept a NULL pointer, the memory for the vfio_matrix_dev object is never freed.

Since the device being released is contained within the vfio_matrix_dev object, the container_of macro will be used to retrieve its pointer.
