CVE-2024-58017

In the Linux kernel, the following vulnerability has been resolved:

printk: Fix signed integer overflow when defining LOG_BUF_LEN_MAX

Shifting 1 << 31 on a 32-bit int causes signed integer overflow, which
leads to undefined behavior. To prevent this, cast 1 to u32 before
performing the shift, ensuring well-defined behavior.

This change explicitly avoids any potential overflow by ensuring that
the shift occurs on an unsigned 32-bit integer.
