| Subject: CVE-2022-48722: net: ieee802154: ca8210: Stop leaking skb's |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ieee802154: ca8210: Stop leaking skb's |
| |
| Upon error the ieee802154_xmit_complete() helper is not called. Only |
| ieee802154_wake_queue() is called manually. We then leak the skb |
| structure. |
| |
| Free the skb structure upon error before returning. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48722 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: |
