Memory Corruption when processing registry values with incorrect types using a direct query method.
AnalysisAI
Memory corruption in Qualcomm Snapdragon's registry value processing exposes devices to potential code execution by high-privileged local attackers. The flaw, rooted in CWE-120 (classic buffer overflow), is triggered when a direct query method processes registry values supplied with incorrect types - bypassing proper type-length validation and corrupting adjacent memory. While the full C:H/I:H/A:H impact triad indicates serious consequences if reached, the PR:H (high privilege) and AV:L (local) CVSS metrics substantially narrow the realistic attack surface. No public exploit code exists and this CVE is not listed in CISA KEV at time of analysis.
Technical ContextAI
The vulnerability resides in the Qualcomm Snapdragon platform (CPE: cpe:2.3:a:qualcomm,_inc.:snapdragon:*:*:*:*:*:*:*:*), a widely deployed system-on-chip family used across Android mobile devices and embedded systems. CWE-120 ('Buffer Copy without Checking Size of Input') identifies the root cause: a buffer copy operation that does not verify the input length against the destination buffer capacity. In this instance, a direct registry query method fails to validate the data type of the registry value being read - when a caller supplies a value whose declared type does not match what the consumer expects, the mismatch likely causes the method to copy a different-sized data block than the buffer was allocated for, resulting in heap or stack memory corruption. Registry interactions on Qualcomm platforms are typically mediated through kernel or trusted-environment interfaces, meaning this flaw may reside in a privileged execution context.
RemediationAI
Apply the patches detailed in the Qualcomm August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html). Patch available per vendor advisory; however, exact patched firmware or driver versions are not independently confirmed from the available reference data - consult the bulletin directly for version-specific remediation targets. Because Snapdragon patches are delivered to end users through OEM device firmware updates (e.g., Android security patches from Samsung, Google, Xiaomi, etc.), organizations should monitor their device vendors' August 2026 or subsequent security update releases and apply them promptly. As a compensating control where patching is delayed, restrict the ability of high-privilege processes to invoke untrusted registry queries, and limit the attack surface by enforcing the principle of least privilege - ensuring only necessary processes hold the elevated access required to reach this code path. Note that the PR:H prerequisite means this flaw is not reachable by standard unprivileged user-space applications without prior privilege escalation.
