How to fix?

Upgrade SLES:15.6 kernel-source to version 6.4.0-150600.23.47.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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.
