- Summary
- [none]
- Details

In the Linux kernel, the following vulnerability has been resolved:
printk: Fix signed integer overflow when defining LOGBUFLEN_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.
