AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
IOCTL exploitation requires local low-privilege process access (AV:L, PR:L); no special configuration needed (AC:L); kernel memory corruption yields full C/I/A impact with no scope change.

Memory Corruption while processing IOCTL device driver requests with invalid arguments.
AnalysisAI
Memory corruption in Qualcomm Snapdragon IOCTL device driver handling enables a local low-privilege attacker to achieve full confidentiality, integrity, and availability impact on the affected system. The flaw (CWE-822: Untrusted Pointer Dereference) allows a process to supply invalid pointer arguments via IOCTL calls that the driver dereferences without adequate validation, corrupting kernel memory. No public exploit code or CISA KEV listing has been identified at time of analysis; however, kernel-level driver bugs in Snapdragon have historically been chained with initial-access exploits to achieve full Android device compromise.
Technical ContextAI
The vulnerability exists within a Qualcomm Snapdragon device driver that services IOCTL (Input/Output Control) requests - a standard syscall interface allowing userspace processes to issue device-specific commands to kernel-mode drivers. CWE-822 (Untrusted Pointer Dereference) identifies the root cause: the driver accepts pointer values or structured arguments from the calling process and dereferences them in kernel context without sufficient validation of their legitimacy or bounds. When invalid arguments are supplied, the driver corrupts kernel memory, which can be leveraged for privilege escalation. The CPE string cpe:2.3:a:qualcomm,_inc.:snapdragon covers the Snapdragon application processor platform, a broadly deployed SoC family found in Android handsets, tablets, IoT devices, and automotive systems. The tags 'Buffer Overflow' and 'Snapdragon' corroborate that the corruption is memory-write oriented, consistent with a bad-pointer dereference leading to an out-of-bounds write.
RemediationAI
The primary remediation is to apply the patch detailed in Qualcomm's August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html). Qualcomm's patch distribution model requires OEMs to integrate fixes into device-specific firmware releases; end users and enterprise administrators should apply the latest available security update from their device manufacturer or MDM-managed update channel without delay. As a compensating control where patching is not immediately feasible, restricting untrusted application installation (e.g., disabling sideloading, enforcing app store policies via MDM) reduces the attacker's ability to obtain the low-privilege code execution needed to reach the vulnerable IOCTL interface - though this does not eliminate risk if another foothold is available. An exact patched driver or firmware version number is not independently confirmed from the available reference data; the bulletin should be consulted for precise version guidance.
