| Subject: CVE-2024-53682: regulator: axp20x: AXP717: set ramp_delay |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| regulator: axp20x: AXP717: set ramp_delay |
| |
| AXP717 datasheet says that regulator ramp delay is 15.625 us/step, |
| which is 10mV in our case. |
| |
| Add a AXP_DESC_RANGES_DELAY macro and update AXP_DESC_RANGES macro to |
| expand to AXP_DESC_RANGES_DELAY with ramp_delay = 0 |
| |
| For DCDC4, steps is 100mv |
| |
| Add a AXP_DESC_DELAY macro and update AXP_DESC macro to |
| expand to AXP_DESC_DELAY with ramp_delay = 0 |
| |
| This patch fix crashes when using CPU DVFS. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53682 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: |
| https://git.kernel.org/stable/c/10eb845a87193ef922cd002e0ff4f4759c1e918d |
