In its November 2024 security update, Google fixed 40 vulnerabilities in Android, including two that are actively exploited: CVE-2024-43047 and CVE-2024-43093.
Google’s announcement gives minimal information about the exploitation, stating only that “there are indications that the following may be under limited, targeted exploitation.”

CVE-2024-43047 is a critical vulnerability (CVSS 7.8) found in Qualcomm’s Digital Signal Processor (DSP) service. Discovered by Google Project Zero, Amnesty International’s Security Lab, and researcher Conghui Wang, this zero-day issue affects many Qualcomm chipsets. Exploiting this use-after-free vulnerability could allow attackers to gain higher privileges and compromise devices. Qualcomm released a patch in October, and its inclusion in the November Android security update will ensure wider distribution and fixes.
The update is crucial due to the active exploitation of CVE-2024-43093, a privilege escalation vulnerability affecting Android versions 12, 13, 14, and 15. This flaw puts a large part of the Android ecosystem at risk.
In typical fashion, Google is delivering the update in two patch levels:
November 1 Patch Level (2024-11-01): Focuses on important Android parts, like the system and framework.
November 5 Patch Level (2024-11-05): Targets vulnerabilities in specific hardware components, including those from Qualcomm, MediaTek, and Imagination Technologies.
Android users should install the November security update immediately when it’s available. Quick action is essential to protect against the active exploitation of vulnerabilities.
