Description OSIDB Bzimport 2024-10-21 13:07:23 UTC
In the Linux kernel, the following vulnerability has been resolved:

ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate()

The psc->div[] array has psc->num_div elements.  These values come from
when we call clk_hw_register_div().  It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on.  So this condition needs to be >=
instead of > to prevent an out of bounds read.
