CVE-2023-32889: Mediatek Baseband Buffer Overflow During SDP mode-set Parsing
An attacker sending a malformed SIP message over VoLTE to a device with a Mediatek baseband can trigger the vulnerability described here. The impact is intra-structure overflow in the baseband, triggered by malformed SDP data in VoLTE message such as SIP INVITE or MESSAGE request. The vulnerability described in this advisory affected a wide range of Mediatek devices. The January 2024 issue of the Mediatek Security Bulletin contains this vulnerability as CVE-2023-32889. Vulnerability Details When a SIP message contains SDP data, first the cc_call_unpack_sdpmsg routine is invoked to unpack the message bytes into an internal representation (sdp_message_struct). Based on that, later, the session object’s des_audio structure is populated with the AMR/AMR-WB codec info.
