CVE-2024-53161: EDAC/bluefield: Fix potential integer overflow
First published: Tue Dec 24 2024(Updated: )
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.
