Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.3
Description
The issue is related to errors in handling the
mmap min addr variable in the LIST POISON function of the Linux kernel. This can allow a remote attacker to bypass a protection mechanism by triggering the use of an uninitialized list entry.Recommendations
For Linux kernel versions prior to 4.3, update to version 4.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the
mmap min addr variable to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
