Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.50

Description The issue arises when the service locator server is restarted quickly, allowing the PDR to concurrently rewrite locator addr fields. To address this, the modification of these fields is protected by placing them under the main pdr->lock.

Recommendations Update to Linux kernel version 6.6.50 or later to resolve the issue. As a temporary workaround, consider restricting concurrent access to the locator addr fields until a patch is available.
