| Subject: CVE-2024-26839: IB/hfi1: Fix a memleak in init_credit_return |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| IB/hfi1: Fix a memleak in init_credit_return |
| |
| When dma_alloc_coherent fails to allocate dd->cr_base[i].va, |
| init_credit_return should deallocate dd->cr_base and |
| dd->cr_base[i] that allocated before. Or those resources |
| would be never freed and a memleak is triggered. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26839 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: |
