| Subject: CVE-2024-38584: net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe() |
| |
| In the prueth_probe() function, if one of the calls to emac_phy_connect() |
| fails due to of_phy_connect() returning NULL, then the subsequent call to |
| phy_attached_info() will dereference a NULL pointer. |
| |
| Check the return code of emac_phy_connect and fail cleanly if there is an |
| error. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38584 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: |
