This series fixes three small bugs discovered in the LTP core library:

1. tst_timer_test: Check array bounds before accessing samples array in
   do_timer_test(), avoiding heap out-of-bounds reads when all samples
   are outliers or early wakeups.
2. tst_memutils: Use proper half-open interval overlap check in
   tst_mapping_in_range(), correctly identifying enclosed mappings and
   avoiding false positives on adjacent mappings.
3. tst_kconfig: Stop scanning at string termination in
   kconfig_parse_line(), avoiding stack buffer overreads when config
   lines do not end with whitespace.
