  3. CVE-2022-49189
In the Linux kernel, the following vulnerability has been resolved: clk: qcom: clk-rcg2: Update logic to calculate D value for RCG The display pixel clock has a requirement on certain newer platforms to support M/N as (2/3) and the final D value calculated results in underflow errors. As the current implementation does not check for D value is within the accepted range for a given M & N value. Update the logic to calculate the final D value based on the range.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: clk: qcom: clk-rcg2: Actualizar la lógica para calcular el valor D para RCG El reloj de píxeles de la pantalla tiene un requisito en ciertas plataformas más nuevas para admitir M/N como (2/3) y el valor D final calculado da como resultado errores de desbordamiento. Como la implementación actual no verifica que el valor D esté dentro del rango aceptado para un valor M & N dado. Actualice la lógica para calcular el valor D final según el rango.
