| Subject: CVE-2024-58010: binfmt_flat: Fix integer overflow bug on 32 bit systems |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| binfmt_flat: Fix integer overflow bug on 32 bit systems |
| |
| Most of these sizes and counts are capped at 256MB so the math doesn't |
| result in an integer overflow. The "relocs" count needs to be checked |
| as well. Otherwise on 32bit systems the calculation of "full_data" |
| could be wrong. |
| |
| full_data = data_len + relocs * sizeof(unsigned long); |
| |
| The Linux kernel CVE team has assigned CVE-2024-58010 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: |
