[PATCH 6.2 604/663] hte: tegra-194: Fix off by one in tegra_hte_map_to_line_id()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit e078180d66848a6a890daf0a3ce28dc43cc66790 ]

The "map_sz" is the number of elements in the "m" array so the >
comparison needs to be changed to >= to prevent an out of bounds
read.

Fixes: 09574cca6ad6 ("hte: Add Tegra194 HTE kernel provider")
