Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, specifically in the clk: bcm: rpi component. The issue arises from a while loop in the raspberrypi discover clocks() function that assumes the id of the last clock element is zero. However, since this data comes from the Videocore firmware, which does not guarantee such behavior, it could lead to out-of-bounds access. The fix involves providing a sentinel element to prevent this issue.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
