Subject: mtd: intflmount: fix off by one error in INFTL_dumpVUchains()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e8e6c875658c39624fc8cb4c6f3e1b6ab9ce1b6e;p=linux-beck.git

mtd: intflmount: fix off by one error in INFTL_dumpVUchains()

The ->PUtable[] array has "->nb_blocks" number of elemetns so this
comparison should be ">=" instead of ">".  Otherwise it could result in
a minor read beyond the end of an array.
