Denial of Service in Samsung Exynos modem SDP format type handling
CVE-2023-24033 affects Samsung Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, and Exynos Auto T512 baseband modem chipsets. According to the provided content, the vulnerability exists because the modem firmware does not properly validate or check format types specified by the Session Description Protocol (SDP) module. Improper handling of attacker-controlled or malformed SDP format type data can cause the baseband to enter a denial-of-service condition. The supplied description specifically supports a parsing/validation flaw in SDP processing leading to modem instability or failure; although mention contexts reference broader Exynos modem remote code execution research, the provided vulnerability-specific description only substantiates denial of service for this CVE.
