CVE-2023-32874: Mediatek Baseband Excessive Number of SDP rtpmap Entries Leads to Stack Buffer Overflow
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 stack buffer 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-2023-32874.
