| Subject: CVE-2024-50074: parport: Proper fix for array out-of-bounds access |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| parport: Proper fix for array out-of-bounds access |
| |
| The recent fix for array out-of-bounds accesses replaced sprintf() |
| calls blindly with snprintf(). However, since snprintf() returns the |
| would-be-printed size, not the actually output size, the length |
| calculation can still go over the given limit. |
| |
| Use scnprintf() instead of snprintf(), which returns the actually |
| output letters, for addressing the potential out-of-bounds access |
| properly. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50074 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: |
