| Subject: CVE-2024-53161: EDAC/bluefield: Fix potential integer overflow |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53161 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
