CVE-2024-53034 is a high-severity Untrusted Pointer Dereference (CWE-822) vulnerability in Qualcomm Fastconnect 6900 Firmware. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 30.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly validates invalid Kernel Mode CPU event and sync object handles passed in Escape calls to prevent untrusted pointer dereference and memory corruption.
Implements memory safeguards to protect against corruption from improper operations on invalid handles with the DriverKnownEscape flag reset.
Ensures timely installation of Qualcomm patches specifically addressing this memory corruption vulnerability as detailed in their security bulletin.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Local kernel memory corruption in Qualcomm driver enables privilege escalation from low-privileged context via untrusted pointer/memory buffer issues.
NVD Description
Memory corruption occurs during an Escape call if an invalid Kernel Mode CPU event and sync object handle are passed with the DriverKnownEscape flag reset.
Deeper analysisAI
CVE-2024-53034 is a memory corruption vulnerability that occurs during an Escape call when an invalid Kernel Mode CPU event and sync object handle are passed with the DriverKnownEscape flag reset. It affects Qualcomm software components, as documented in the vendor's security bulletin. The issue is associated with CWE-822 (Untrusted Pointer Dereference) and CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), and it received a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity.
A local attacker with low privileges can exploit this vulnerability with low attack complexity and no user interaction required. Exploitation triggers memory corruption, potentially enabling high-impact outcomes such as unauthorized data access, modification of system integrity, or denial of service through kernel instability.
Qualcomm's March 2025 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/march-2025-bulletin.html) addresses the vulnerability, providing guidance on affected products and available patches for mitigation. Security practitioners should review the bulletin for specific remediation steps tailored to deployed Qualcomm platforms.
