Descriptions
A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures.
Una fuga de memoria en la función kernel_read_file en fs/exec.c en el kernel de Linux, hasta la versión 4.20.11, permite que los atacantes provoquen una denegación de servicio (consumo de memoria) desencadenando errores en vfs_read.
A kernel memory leak was found in the kernel_read_file() function in the fs/exec.c file in the Linux kernel. An attacker could use this flaw to cause a memory leak and thus a denial of service (DoS).
