| Subject: CVE-2024-52559: drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit() |
| |
| The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32 |
| values that come from the user via the submit_lookup_cmds() function. |
| This addition could lead to an integer wrapping bug so use size_add() |
| to prevent that. |

| 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: |
