| Subject: CVE-2023-53019: net: mdio: validate parameter addr in mdiobus_get_phy() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: mdio: validate parameter addr in mdiobus_get_phy() |
| |
| The caller may pass any value as addr, what may result in an out-of-bounds |
| access to array mdio_map. One existing case is stmmac_init_phy() that |
| may pass -1 as addr. Therefore validate addr before using it. |
| |
| The Linux kernel CVE team has assigned CVE-2023-53019 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: |
