In the Linux kernel, the following vulnerability has been resolved:
of: fix out-of-bounds read in of_alias_scan() stem parser
The stem parser tests isdigit(*(end - 1)) before checking end > start
and so reads one byte before the property name when the name is empty
or all digits. Check the bound first.
