Summary
net: sparx5: Fix use after free inside sparx5_del_mact_entry
Details

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

net: sparx5: Fix use after free inside sparx5delmact_entry

Based on the static analyzis of the code it looks like when an entry from the MAC table was removed, the entry was still used after being freed. More precise the vid of the macentry was used after calling devmkfree on the macentry. The fix consists in first using the vid of the macentry to delete the entry from the HW and after that to free it.
