| Subject: CVE-2024-38603: drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() |
| |
| pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action() |
| fails, the irq vector is not freed, which leads to a memory leak. |
| |
| Replace the devm_add_action with devm_add_action_or_reset to ensure |
| the irq vector can be destroyed when it fails. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38603 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: |
