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.
