| Subject: CVE-2024-46758: hwmon: (lm95234) Fix underflows seen when writing limit attributes |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| hwmon: (lm95234) Fix underflows seen when writing limit attributes |
| |
| DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large |
| negative number such as -9223372036854775808 is provided by the user. |
| Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations. |
| |
| The Linux kernel CVE team has assigned CVE-2024-46758 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: |
