NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel 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:

firmware_loader: Fix use-after-free during unregister

In the following code within firmware_upload_unregister(), the call to device_unregister() could result in the dev_release function freeing the fw_upload_priv structure before it is dereferenced for the call to module_put(). This bug was found by the kernel test robot using CONFIG_KASAN while running the firmware selftests.

device_unregister(&fw_sysfs->dev); module_put(fw_upload_priv->module);

The problem is fixed by copying fw_upload_priv->module to a local variable for use when calling device_unregister().
