CVE-2024-58017 MEDIUM

Published: 2025-02-27 | Last Modified: 2026-05-12 | Status: Modified

Description

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.

Additional Descriptions (1)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: printk: Se corrige el desbordamiento de entero con signo al definir LOG_BUF_LEN_MAX. El cambio de 1 &lt;&lt; 31 en un entero de 32 bits provoca un desbordamiento de entero con signo, lo que conduce a un comportamiento indefinido. Para evitarlo, convierta 1 a u32 antes de realizar el cambio, lo que garantiza un comportamiento bien definido. Este cambio evita explícitamente cualquier desbordamiento potencial al garantizar que el cambio se produzca en un entero de 32 bits sin signo.
