| Subject: CVE-2024-26593: i2c: i801: Fix block process call transactions |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| i2c: i801: Fix block process call transactions |
| |
| According to the Intel datasheets, software must reset the block |
| buffer index twice for block process call transactions: once before |
| writing the outgoing data to the buffer, and once again before |
| reading the incoming data from the buffer. |
| |
| The driver is currently missing the second reset, causing the wrong |
| portion of the block buffer to be read. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26593 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: |
