| Subject: CVE-2024-56557: iio: adc: ad7923: Fix buffer overflow for tx_buf and ring_xfer |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| iio: adc: ad7923: Fix buffer overflow for tx_buf and ring_xfer |
| |
| The AD7923 was updated to support devices with 8 channels, but the size |
| of tx_buf and ring_xfer was not increased accordingly, leading to a |
| potential buffer overflow in ad7923_update_scan_mode(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-56557 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: |
