| Subject: CVE-2024-50051: spi: mpc52xx: Add cancel_work_sync before module remove |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| spi: mpc52xx: Add cancel_work_sync before module remove |
| |
| If we remove the module which will call mpc52xx_spi_remove |
| it will free 'ms' through spi_unregister_controller. |
| while the work ms->work will be used. The sequence of operations |
| that may lead to a UAF bug. |
| |
| Fix it by ensuring that the work is canceled before proceeding with |
| the cleanup in mpc52xx_spi_remove. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50051 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: |
