In the Linux kernel, the following vulnerability has been resolved:
of: reserved_mem: prevent OOB when too many dynamic regions are defined
On boot, fdt_scan_reserved_mem() saves each dynamically-placed
/reserved-memory subnode into a local array of size
MAX_RESERVED_REGIONS.
If the device tree defines more than MAX_RESERVED_REGIONS
dynamically-placed regions, fdt_scan_reserved_mem() writes past the
end of the local array.
Add a bounds check that logs an error and skips the excess regions,
restoring the original behavior.
