Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> clk: bcm: rpi: Prevent out-of-bounds access<br /> <br /> The while loop in raspberrypi_discover_clocks() relies on the assumption<br /> that the id of the last clock element is zero. Because this data comes<br /> from the Videocore firmware and it doesn&amp;#39;t guarantuee such a behavior<br /> this could lead to out-of-bounds access. So fix this by providing<br /> a sentinel element.
