EDAC/device_sysfs: Use kstrtouint() for poll_msec to prevent truncation

Type: advisorySource: Official CVE List1 source record

In the Linux kernel, the following vulnerability has been resolved: EDAC/device_sysfs: Use kstrtouint() for poll_msec to prevent truncation The poll_msec sysfs store file uses simple_strtoul() which accepts an unsigned long, but the target field (poll_msec) is unsigned int. On 64-bit systems, a value > UINT_MAX is silently truncated when stored. Fix the mismatch by using kstrtouint() instead. This rejects values larger than UINT_MAX at parse time, making truncation impossible. Also add a check for value < 1 to reject the 0-delay case, which would cause the poll work to spin without delay and consume 100% CPU.
