Severity by source
AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
AV:P confirmed by fastboot's mandatory physical USB requirement; PR:N because fastboot mode requires no credentials; S:C because audio handler memory corruption can propagate into privileged firmware scope.

Memory Corruption when processing untrusted user input in the fastboot command handler for audio framework configuration.
AnalysisAI
Memory corruption in Qualcomm Snapdragon's fastboot command handler for audio framework configuration allows an attacker with physical USB access to a device in bootloader mode to send malformed input and trigger memory corruption with cross-scope impact - potentially reaching privileged firmware or TrustZone-adjacent components (S:C in the CVSS vector). The full confidentiality, integrity, and availability impact (C:H/I:H/A:H) indicates the compromise can extend beyond the vulnerable component itself. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Physical, in-person access to the target device is required - confirmed by AV:P in the CVSS vector; remote exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 7.6 is elevated by the scope change (S:C) and full confidentiality/integrity/availability impact (C:H/I:H/A:H), but the physical attack vector (AV:P) substantially constrains real-world risk - exploitation requires hands-on device access and the ability to boot into fastboot mode. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker gains physical access to a target Android device with a Snapdragon SoC - for example, an unattended unlocked-bootloader handset. They connect via USB, boot the device into fastboot mode using a hardware key combination, and issue a crafted fastboot command targeting the audio framework configuration handler with syntactically malformed input, triggering memory corruption. … |
| Remediation | Apply firmware updates incorporating the Qualcomm-supplied patch as detailed in the August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all Snapdragon devices, document current firmware versions, and identify which devices have accessible bootloader modes or enabled USB debugging. …
