Description OSIDB Bzimport 2025-02-27 03:03:53 UTC
In the Linux kernel, the following vulnerability has been resolved:

OPP: add index check to assert to avoid buffer overflow in _read_freq()

Pass the freq index to the assert function to make sure
we do not read a freq out of the opp->rates[] table when called
from the indexed variants:
dev_pm_opp_find_freq_exact_indexed() or
dev_pm_opp_find_freq_ceil/floor_indexed().

Add a secondary parameter to the assert function, unused
for assert_single_clk() then add assert_clk_index() which
will check for the clock index when called from the _indexed()
find functions.
