| Subject: CVE-2024-35984: i2c: smbus: fix NULL function pointer dereference |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| i2c: smbus: fix NULL function pointer dereference |
| |
| Baruch reported an OOPS when using the designware controller as target |
| only. Target-only modes break the assumption of one transfer function |
| always being available. Fix this by always checking the pointer in |
| __i2c_transfer. |
| |
| [wsa: dropped the simplification in core-smbus to avoid theoretical regressions] |
| |
| The Linux kernel CVE team has assigned CVE-2024-35984 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: |
