Pending analysis
Type:
CWE-125 Out-of-bounds Read

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> clk: microchip: mpfs-ccc: fix out of bounds access during output registration<br /> <br /> UBSAN reported an out of bounds access during registration of the last<br /> two outputs. This out of bounds access occurs because space is only<br /> allocated in the hws array for two PLLs and the four output dividers<br /> that each has, but the defined IDs contain two DLLS and their two<br /> outputs each, which are not supported by the driver. The ID order is<br /> PLLs -&gt; DLLs -&gt; PLL outputs -&gt; DLL outputs. Decrement the PLL output IDs<br /> by two while adding them to the array to avoid the problem.
