| Subject: CVE-2024-56546: drivers: soc: xilinx: add the missing kfree in xlnx_add_cb_for_suspend() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drivers: soc: xilinx: add the missing kfree in xlnx_add_cb_for_suspend() |
| |
| If we fail to allocate memory for cb_data by kmalloc, the memory |
| allocation for eve_data is never freed, add the missing kfree() |
| in the error handling path. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56546 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: |
