Description OSIDB Bzimport 2025-12-30 13:12:45 UTC 
In the Linux kernel, the following vulnerability has been resolved:

of: overlay: fix null pointer dereferencing in find_dup_cset_node_entry() and find_dup_cset_prop()

When kmalloc() fail to allocate memory in kasprintf(), fn_1 or fn_2 will
be NULL, and strcmp() will cause null pointer dereference.
