Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amdgpu: Fix the memory allocation issue in amdgpu_discovery_get_nps_info()<br />
<br />
Fix two issues with memory allocation in amdgpu_discovery_get_nps_info()<br />
for mem_ranges:<br />
<br />
- Add a check for allocation failure to avoid dereferencing a null<br />
pointer.<br />
<br />
- As suggested by Christophe, use kvcalloc() for memory allocation,<br />
which checks for multiplication overflow.<br />
<br />
Additionally, assign the output parameters nps_type and range_cnt after<br />
the kvcalloc() call to prevent modifying the output parameters in case<br />
of an error return.
