Description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper resource management in the NFC subsystem when closing a device. A local user can trigger a memory leak by closing an NFC device while a data exchange is pending, leading to resource exhaustion over time.
Memory is not properly released when a pending data exchange is left uncompleted during device closure, resulting in a gradual loss of available memory.
Remediation
Install security update from vendor's repository.
