Severity ?

Summary

In the Linux kernel, the following vulnerability has been resolved: driver: soc: xilinx: use _safe loop iterator to avoid a use after free The hash_for_each_possible() loop dereferences "eve_data" to get the next item on the list. However the loop frees eve_data so it leads to a use after free. Use hash_for_each_possible_safe() instead.
