| Subject: CVE-2024-42284: tipc: Return non-zero value from tipc_udp_addr2str() on error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| tipc: Return non-zero value from tipc_udp_addr2str() on error |
| |
| tipc_udp_addr2str() should return non-zero value if the UDP media |
| address is invalid. Otherwise, a buffer overflow access can occur in |
| tipc_media_addr_printf(). Fix this by returning 1 on an invalid UDP |
| media address. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42284 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: |
