Description OSIDB Bzimport 2024-10-21 20:03:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

driver core: bus: Fix double free in driver API bus_register()

For bus_register(), any error which happens after kset_register() will
cause that @priv are freed twice, fixed by setting @priv with NULL after
the first free.
