CVE-2024-45564 is a use-after-free vulnerability classified under CWE-416, discovered in Qualcomm Snapdragon platforms. The root cause is an incorrect update of the reference count during concurrent access to a server info object, leading to memory corruption. This flaw arises when multiple threads or processes access and modify the reference count simultaneously without proper synchronization, resulting in premature freeing of memory that is still in use. The affected products include a broad array of Snapdragon chipsets and modules such as C-V2X 9150, FastConnect series, various QCA and SA series chipsets, Snapdragon 8 Gen 1, 865, 888 platforms, and others used in mobile, wearable, automotive, and IoT devices. The vulnerability allows an attacker with low privileges and local access to exploit the memory corruption to execute arbitrary code, escalate privileges, or cause denial of service by crashing the system. The CVSS v3.1 base score is 7.8, with attack vector local (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits are known at this time, but the vulnerability is considered high risk due to the widespread deployment of affected hardware and the potential for impactful exploitation. Qualcomm has not yet published patches, so mitigation currently relies on reducing exposure and monitoring for suspicious activity.

The impact of CVE-2024-45564 is significant for organizations worldwide that use devices powered by affected Qualcomm Snapdragon chipsets. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain unauthorized control over affected devices. This can result in data breaches, unauthorized access to sensitive information, and disruption of critical services. The vulnerability also enables privilege escalation, potentially allowing attackers to bypass security controls and gain higher-level system access. Denial of service attacks could cause device crashes or reboots, impacting availability of services, especially in environments relying on mobile, automotive, or IoT devices. Given the extensive list of affected chipsets used in smartphones, wearables, automotive systems, and network equipment, the scope of impact is broad. Enterprises with mobile workforces, telecom providers, automotive manufacturers, and IoT deployments are particularly vulnerable. The local attack vector and low privilege requirement mean that insider threats or malware with limited access could exploit this flaw. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once patches are released.

To mitigate CVE-2024-45564, organizations should: 1) Monitor Qualcomm and device vendors for official patches and apply them promptly once available. 2) Restrict local access to affected devices by enforcing strict access controls, limiting user privileges, and isolating critical systems. 3) Employ runtime protection mechanisms such as memory corruption mitigations (e.g., Address Space Layout Randomization (ASLR), Control Flow Integrity (CFI), and Data Execution Prevention (DEP)) where supported by the device. 4) Use endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. 5) For environments with shared or multi-user devices, enforce session isolation and limit concurrent access to vulnerable components. 6) Conduct regular security audits and vulnerability assessments focusing on devices with affected Qualcomm hardware. 7) Educate users about the risks of installing untrusted local software or malware that could exploit this vulnerability. 8) Collaborate with device manufacturers to understand the patch deployment timeline and interim mitigation options. These steps go beyond generic advice by focusing on local access restrictions, memory protection features, and proactive monitoring tailored to the vulnerability’s characteristics.
