CVE-2024-43768 is a vulnerability identified in the Skia graphics library component of Google Android, specifically within the skia_alloc_func function in SkDeflate.cpp. The root cause is an integer overflow that leads to an out-of-bounds write condition (CWE-787). This flaw allows a local attacker with limited privileges to write beyond allocated memory boundaries, potentially overwriting critical data structures or code pointers. Such memory corruption can be leveraged to escalate privileges on the device without requiring additional execution privileges or user interaction. The vulnerability affects Android versions 12, 12L, 13, 14, and 15, which cover a broad range of currently supported devices. The CVSS v3.1 base score of 7.8 indicates a high-severity issue with local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are known at this time, the vulnerability's characteristics make it a significant risk for local attackers aiming to gain elevated privileges and potentially compromise device security.

The vulnerability allows local attackers to escalate privileges on affected Android devices, potentially gaining root or system-level access. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, and disruption of device functionality. The compromise of confidentiality, integrity, and availability can facilitate further attacks such as persistent malware installation, data exfiltration, or denial of service. Organizations relying on Android devices for sensitive communications or operations face increased risk of insider threats or malware exploiting this flaw. The lack of required user interaction and low privilege requirements increase the likelihood of exploitation in environments where local access is possible, such as shared devices or compromised endpoints.

1. Apply official security patches from Google or device manufacturers as soon as they become available for affected Android versions (12, 12L, 13, 14, 15). 2. Restrict local access to devices by enforcing strong physical security controls and limiting user privileges to the minimum necessary. 3. Employ mobile device management (MDM) solutions to monitor and control device configurations and detect anomalous behavior indicative of exploitation attempts. 4. Disable or restrict installation of untrusted applications and enforce application whitelisting to reduce the risk of local malware leveraging this vulnerability. 5. Regularly audit devices for signs of compromise, including unexpected privilege escalations or unusual system behavior. 6. Educate users about the risks of granting unnecessary permissions and the importance of applying updates promptly. 7. For highly sensitive environments, consider additional endpoint protection solutions that monitor memory integrity and prevent exploitation of memory corruption vulnerabilities.
