Description OSIDB Bzimport 2025-12-24 14:06:19 UTC 
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.
