| Subject: CVE-2024-27401: firewire: nosy: ensure user_length is taken into account when fetching packet contents |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| firewire: nosy: ensure user_length is taken into account when fetching packet contents |
| |
| Ensure that packet_buffer_get respects the user_length provided. If |
| the length of the head packet exceeds the user_length, packet_buffer_get |
| will now return 0 to signify to the user that no data were read |
| and a larger buffer size is required. Helps prevent user space overflows. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27401 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: |
