Memory Corruption when handling flash commands due to outdated LED count values being used after userspace modification.
AnalysisAI
Out-of-bounds write in Qualcomm Snapdragon's flash command handler allows a local low-privileged attacker to corrupt memory by exploiting a race condition between userspace LED count modifications and kernel-side flash command processing. The CVSS scope change (S:C) indicates the corruption can reach components beyond the immediately vulnerable driver - raising the potential for privilege escalation on affected Snapdragon-based devices. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local, low-privilege process (PR:L, AV:L) - remote unauthenticated exploitation is ruled out by the local attack vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.3 Medium score reflects meaningful but constrained risk: the local attack vector (AV:L) eliminates remote exploitation, low privileges (PR:L) represent a realistic attacker foothold on developer-mode or compromised Android devices, and high attack complexity (AC:H) indicates a race condition timing dependency that reduces reliable exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker with a low-privilege shell on a Snapdragon-based Android device opens the flash LED command interface and issues a flash command while a concurrent thread modifies the userspace LED count value, winning the race to substitute an out-of-range count before the driver re-reads it. The out-of-bounds write corrupts kernel memory in an adjacent component - potentially overwriting function pointers or security-sensitive structures - enabling privilege escalation. … |
| Remediation | Apply patches provided through the Qualcomm July 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/july-2026-bulletin.html); exact patched firmware or driver version numbers are not independently confirmed from the available data - consult the bulletin directly and follow up with the device OEM for platform-specific software updates. … Detailed patch versions, workarounds, and compensating controls in full report. |
