Description OSIDB Bzimport 2025-12-30 13:09:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

hte: tegra-194: Fix off by one in tegra_hte_map_to_line_id()

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.
