Details

In the Linux kernel, the following vulnerability has been resolved: clk: Fix clkhwgetclk() when dev is NULL Any registered clkcore structure can have a NULL pointer in its dev field. While never actually documented, this is evidenced by the wide usage of clkregister and clkhwregister with a NULL device pointer, and the fact that the core ofclkhwregister() function also passes a NULL device pointer. A call to clkhwgetclk() on a clkhw struct whose clkcore is in that case will result in a NULL pointer derefence when it calls devname() on that NULL device pointer. Add a test for this case and use NULL as the dev_id if the device pointer is NULL.
