| Subject: CVE-2024-26684: net: stmmac: xgmac: fix handling of DPP safety error for DMA channels |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: stmmac: xgmac: fix handling of DPP safety error for DMA channels |
| |
| Commit 56e58d6c8a56 ("net: stmmac: Implement Safety Features in |
| XGMAC core") checks and reports safety errors, but leaves the |
| Data Path Parity Errors for each channel in DMA unhandled at all, lead to |
| a storm of interrupt. |
| Fix it by checking and clearing the DMA_DPP_Interrupt_Status register. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26684 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: |
