| Subject: CVE-2024-36946: phonet: fix rtm_phonet_notify() skb allocation |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| phonet: fix rtm_phonet_notify() skb allocation |
| |
| fill_route() stores three components in the skb: |
| |
| - struct rtmsg |
| - RTA_DST (u8) |
| - RTA_OIF (u32) |
| |
| Therefore, rtm_phonet_notify() should use |
| |
| NLMSG_ALIGN(sizeof(struct rtmsg)) + |
| nla_total_size(1) + |
| nla_total_size(4) |
| |
| The Linux kernel CVE team has assigned CVE-2024-36946 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: |
