| Subject: CVE-2024-26744: RDMA/srpt: Support specifying the srpt_service_guid parameter |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| RDMA/srpt: Support specifying the srpt_service_guid parameter |
| |
| Make loading ib_srpt with this parameter set work. The current behavior is |
| that setting that parameter while loading the ib_srpt kernel module |
| triggers the following kernel crash: |
| |
| BUG: kernel NULL pointer dereference, address: 0000000000000000 |
| Call Trace: |

| 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: |
