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