CVE-2018-5891 is a vulnerability of currently unknown severity. While processing modem SSR after IMS is registered, the IMS data daemon is restarted but the ipc_dataHandle is no longer available. Consequently, the DPL thread frees the internal memory for dataDHandle but the local variable pointer is not updated which can lead to a Use After Free condition in Snapdragon Mobile and Snapdragon Wear.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
