| Subject: CVE-2022-49581: be2net: Fix buffer overflow in be_get_module_eeprom |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| be2net: Fix buffer overflow in be_get_module_eeprom |
| |
| be_cmd_read_port_transceiver_data assumes that it is given a buffer that |
| is at least PAGE_DATA_LEN long, or twice that if the module supports SFF |
| 8472. However, this is not always the case. |
| |
| Fix this by passing the desired offset and length to |
| be_cmd_read_port_transceiver_data so that we only copy the bytes once. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49581 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: |
