Description
In the Linux kernel, the following vulnerability has been resolved:
EDAC/bluefield: Fix potential integer overflow
The 64-bit argument for the "get DIMM info" SMC call consists of mem_ctrl_idx
left-shifted 16 bits and OR-ed with DIMM index. With mem_ctrl_idx defined as
32-bits wide the left-shift operation truncates the upper 16 bits of
information during the calculation of the SMC argument.
The mem_ctrl_idx stack variable must be defined as 64-bits wide to prevent any
potential integer overflow, i.e. loss of data from upper 16 bits.
