Description
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-wmi-sysman: bound enumeration string aggregation
populate_enum_data() aggregates firmware-provided value-modifier
and possible-value strings into fixed 512-byte struct members.
The current code bounds each individual source string but then
appends every string and separator with raw strcat() and no
remaining-space check.
Switch the aggregation loops to a bounded append helper and
reject enumeration packages whose combined strings do not fit
in the destination buffers.
