| Subject: CVE-2024-46861: usbnet: ipheth: do not stop RX on failing RX callback |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| usbnet: ipheth: do not stop RX on failing RX callback |
| |
| RX callbacks can fail for multiple reasons: |
| |
| * Payload too short |
| * Payload formatted incorrecly (e.g. bad NCM framing) |
| * Lack of memory |
| |
| None of these should cause the driver to seize up. |
| |
| Make such failures non-critical and continue processing further |
| incoming URBs. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46861 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: |
| https://git.kernel.org/stable/c/4d1cfa3afb8627435744ecdc6d8b58bc72ee0f4c |
