In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix incorrect list API usage
Both the function that migrates all the chunks within a region and the function that migrates all the entries within a chunk call list_first_entry() on the respective lists without checking that the lists are not empty. This is incorrect usage of the API, which leads to the following warning [1].
Fix by returning if the lists are empty as there is nothing to migrate in this case.
