Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local DSP/driver bug needing a low-privilege foothold (PR:L) and winning a thread race window (AC:H); use-after-free yields full memory compromise so C/I/A:H, scope unchanged.

Memory Corruption when asynchronous threads access shared performance counter data simultaneously during FastRPC invocations.
AnalysisAI
Memory corruption via a use-after-free in the FastRPC implementation on Qualcomm Snapdragon platforms allows a local attacker with low-privilege code execution to escalate privileges and compromise confidentiality, integrity, and availability of the affected device. Triggering the bug requires a pre-existing foothold - code able to open the FastRPC driver interface and drive DSP invocations - plus concurrent asynchronous threads that race shared performance counter data, so successful exploitation depends on winning a timing window rather than a deterministic primitive. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires local code execution on the affected Snapdragon device with the ability to perform FastRPC invocations (interacting with the DSP via the FastRPC driver interface) - PR:L indicates some authenticated/low-privilege context is needed, not an unauthenticated remote attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but not emergency-grade priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Because the fix lives in Qualcomm's platform software, the primary remediation is to apply the OEM firmware/OTA update that incorporates the vendor's October 2026 bulletin patch for the affected Snapdragon platform; the per-chipset fixed version is not enumerated in the data provided here and must be taken from https://docs.qualcomm.com/product/publicresources/securitybulletin/october-2026-bulletin.html together with the device manufacturer's corresponding update. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Qualcomm Snapdragon-based devices and determine exposure to the FastRPC driver interface, then restrict local access to the FastRPC driver where operationally feasible. …
