NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.
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().
