CVE-2026-43281

Summary
In the Linux kernel, the following vulnerability has been resolved:
mailbox: Prevent out-of-bounds access in fw_mbox_index_xlate()
Although it is guided that #mbox-cells must be at least 1, there are
many instances of #mbox-cells = <0>; in the device tree. If that is
the case and the corresponding mailbox controller does not provide
fw_xlate and of_xlatefunction pointers,fw_mbox_index_xlate()` will
be used by default and out-of-bounds accesses could occur due to lack of
bounds check in that function.
