CVE-2025-38390
MEDIUMDescription
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_ffa: Fix memory leak by freeing notifier callback node
Commit e0573444edbf ("firmware: arm_ffa: Add interfaces to request
notification callbacks") adds support for notifier callbacks by allocating
and inserting a callback node into a hashtable during registration of
notifiers. However, during unregistration, the code only removes the
node from the hashtable without freeing the associated memory, resulting
in a memory leak.
Resolve the memory leak issue by ensuring the allocated notifier callback
node is properly freed after it is removed from the hashtable entry.
