Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> firmware: arm_ffa: Fix memory leak by freeing notifier callback node<br /> <br /> Commit e0573444edbf ("firmware: arm_ffa: Add interfaces to request<br /> notification callbacks") adds support for notifier callbacks by allocating<br /> and inserting a callback node into a hashtable during registration of<br /> notifiers. However, during unregistration, the code only removes the<br /> node from the hashtable without freeing the associated memory, resulting<br /> in a memory leak.<br /> <br /> Resolve the memory leak issue by ensuring the allocated notifier callback<br /> node is properly freed after it is removed from the hashtable entry.
