Description
In the Linux kernel, the following vulnerability has been resolved:
clk: bcm: rpi: Prevent out-of-bounds access
The while loop in raspberrypi_discover_clocks() relies on the assumption
that the id of the last clock element is zero. Because this data comes
from the Videocore firmware and it doesn't guarantuee such a behavior
this could lead to out-of-bounds access. So fix this by providing
a sentinel element.
Affected configurations
• linux linux kernel (>= 5.9 < 5.10.142)
• linux linux kernel (>= 5.11 < 5.15.66)
• linux linux kernel (>= 5.16 < 5.19.8)
• linux linux kernel 6.0
