CVE-2024-53161 is a medium severity vulnerability in the Linux kernel's EDAC/bluefield component involving a potential integer overflow. The issue arises because a 32-bit mem_ctrl_idx variable is left-shifted 16 bits and combined with a DIMM index into a 64-bit argument, causing truncation of the upper 16 bits. This can lead to loss of critical data during the calculation of the SMC call argument. The vulnerability has been fixed by redefining mem_ctrl_idx as a 64-bit variable to prevent overflow.
