| Subject: CVE-2024-57938: net/sctp: Prevent autoclose integer overflow in sctp_association_init() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net/sctp: Prevent autoclose integer overflow in sctp_association_init() |
| |
| While by default max_autoclose equals to INT_MAX / HZ, one may set |
| net.sctp.max_autoclose to UINT_MAX. There is code in |
| sctp_association_init() that can consequently trigger overflow. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57938 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: |
