Descriptions

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.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: arm_ffa: Corregir fuga de memoria liberando el nodo de devolución de llamada del notificador. El commit e0573444edbf ("firmware: arm_ffa: Añadir interfaces para solicitar devoluciones de llamada de notificación") añade compatibilidad con devoluciones de llamada de notificador mediante la asignación e inserción de un nodo de devolución de llamada en una tabla hash durante el registro de notificadores. Sin embargo, al anular el registro, el código solo elimina el nodo de la tabla hash sin liberar la memoria asociada, lo que provoca una fuga de memoria. Para resolver el problema de fuga de memoria, asegúrese de que el nodo de devolución de llamada del notificador asignado se libere correctamente tras eliminarlo de la entrada de la tabla hash.
