  3. CVE-2024-47686
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate() La matriz psc->div[] tiene elementos psc->num_div. Estos valores provienen de cuando llamamos a clk_hw_register_div(). Son adc_divisors y ARRAY_SIZE(adc_divisors)) y así sucesivamente. Por lo tanto, esta condición debe ser >= en lugar de > para evitar una lectura fuera de los límites.
