CVE-2023-53595

What is CVE-2023-53595?

This vulnerability in the Linux kernel is associated with the macsec interface, where improper handling during system reboot can lead to null pointer dereferences. This situation arises specifically after creating a macsec interface. The bug can cause system crashes, resulting in disruptions, especially in environments that rely on stable network functions. A patch has been implemented to resolve this issue by ensuring the correct order of teardown operations, thus preventing the occurrence of null pointer dereferences when the system is rebooted.
