What to Know

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. (NVD)
