| Subject: CVE-2024-38619: usb-storage: alauda: Check whether the media is initialized |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usb-storage: alauda: Check whether the media is initialized |
| |
| The member "uzonesize" of struct alauda_info will remain 0 |
| if alauda_init_media() fails, potentially causing divide errors |
| in alauda_read_data() and alauda_write_lba(). |
| - Add a member "media_initialized" to struct alauda_info. |
| - Change a condition in alauda_check_media() to ensure the |
| first initialization. |
| - Add an error check for the return value of alauda_init_media(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-38619 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: |
