Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.5.2

Description A use-after-free issue exists, allowing local users to cause a denial of service, potentially resulting in memory corruption, system crash, or spinlock. This issue is related to the removal of a network namespace and involves the (ppp register net channel) and (ppp unregister channel) functions.

Recommendations For versions prior to 4.5.2, update to version 4.5.2 or later to resolve the issue. As a temporary workaround, consider restricting the removal of network namespaces to minimize the risk of exploitation.
