| Subject: CVE-2022-48743: net: amd-xgbe: Fix skb data length underflow |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: amd-xgbe: Fix skb data length underflow |
| |
| There will be BUG_ON() triggered in include/linux/skbuff.h leading to |
| intermittent kernel panic, when the skb length underflow is detected. |
| |
| Fix this by dropping the packet if such length underflows are seen |
| because of inconsistencies in the hardware descriptors. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48743 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: |
