Description

A vulnerability was found in the Linux kernel's memory management subsystem where a lack of proper size checks on dirty limits can lead to situations where large dirty limits end up being larger than 32-bits, resulting in potential overflows and divisions by 0. This can cause memory corruption, system instability, or crashes.

Statement

Red Hat believes this flaw is moderate severity because the privileges necessary to exploit this vulnerability are high, as it requires a user to have elevated permissions to set the dirty page limits.
