| Subject: CVE-2025-22006: net: ethernet: ti: am65-cpsw: Fix NAPI registration sequence |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ethernet: ti: am65-cpsw: Fix NAPI registration sequence |
| |
| Registering the interrupts for TX or RX DMA Channels prior to registering |
| their respective NAPI callbacks can result in a NULL pointer dereference. |
| This is seen in practice as a random occurrence since it depends on the |
| randomness associated with the generation of traffic by Linux and the |
| reception of traffic from the wire. |
| |
| The Linux kernel CVE team has assigned CVE-2025-22006 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: |
