Description OSIDB Bzimport 2025-02-26 03:10:31 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: sparx5: switchdev: fix possible NULL pointer dereference

As the possible failure of the allocation, devm_kzalloc() may return NULL
pointer.
Therefore, it should be better to check the 'db' in order to prevent
the dereference of NULL pointer.
