| Subject: CVE-2024-56601: net: inet: do not leave a dangling sk pointer in inet_create() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: inet: do not leave a dangling sk pointer in inet_create() |
| |
| sock_init_data() attaches the allocated sk object to the provided sock |
| object. If inet_create() fails later, the sk object is freed, but the |
| sock object retains the dangling pointer, which may create use-after-free |
| later. |
| |
| Clear the sk pointer in the sock object on error. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56601 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: |
