|---|---|---|---|
| 2024-03-25 | CVE-2021-47150 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: fec: fix the potential memory leak in fec_enet_init() If the memory allocated for cbd_base is failed, it should free the memory allocated for the queues, otherwise it causes memory leak. And if the memory allocated for the queues is failed, it can return error directly. | 5.5 |
