| Subject: CVE-2024-47686: ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate() |
| |
| The psc->div[] array has psc->num_div elements. These values come from |
| when we call clk_hw_register_div(). It's adc_divisors and |
| ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >= |
| instead of > to prevent an out of bounds read. |
| |
| The Linux kernel CVE team has assigned CVE-2024-47686 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: |
