| Subject: CVE-2024-35972: bnxt_en: Fix possible memory leak in bnxt_rdma_aux_device_init() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| bnxt_en: Fix possible memory leak in bnxt_rdma_aux_device_init() |
| |
| If ulp = kzalloc() fails, the allocated edev will leak because it is |
| not properly assigned and the cleanup path will not be able to free it. |
| Fix it by assigning it properly immediately after allocation. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35972 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: |
