| Subject: CVE-2024-38560: scsi: bfa: Ensure the copied buf is NUL terminated |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: bfa: Ensure the copied buf is NUL terminated |
| |
| Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from |
| userspace to that buffer. Later, we use sscanf on this buffer but we don't |
| ensure that the string is terminated inside the buffer, this can lead to |
| OOB read when using sscanf. Fix this issue by using memdup_user_nul instead |
| of memdup_user. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38560 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: |
