Title
mtd: maps: vmu-flash: fix fault in unaligned fixup
Summary
In the Linux kernel, the following vulnerability has been resolved: mtd: maps: vmu-flash: fix fault in unaligned fixup Use kzalloc_obj() / kzalloc_objs() to allocate the memcard structs, instead of kmalloc_obj() / kmalloc_objs() to prevent access to uninitialized data. Fixes runtime error: Fault in unaligned fixup: 0000 [#1] at mtd_get_fact_prot_info.
