CVE Alert: CVE-2025-47316 – Qualcomm, Inc. – Snapdragon
CVE-2025-47316
Memory corruption due to double free when multiple threads race to set the timestamp store.
AI Summary Analysis
Risk verdict
High risk of local memory corruption in Snapdragon video components via a double-free race, with no explicit KEV/EPSS signals shown; treat as priority 2 unless exploitation indicators emerge.
Why this matters
A successful local exploitation could crash or allow control of the video processing path, risking data confidentiality, integrity, and availability on affected devices. Given widespread Snapdragon deployments in mobile, automotive, and IoT, an attacker podría leverage this to escalate within a device or pivot to adjacent components where video workloads run.
Most likely attack path
Exploitation requires local access with low privileges and no user interaction. The attacker would exploit a race between threads setting the timestamp store to trigger a double-free, potentially leading to memory corruption and remote-like impact within the video subsystem. The scope is unchanged, so successful abuse could compromise the affected component without broader system permissions, depending on memory layout and mitigations.
Who is most exposed
Devices relying on Qualcomm Snapdragon SoCs that perform video processing are exposed, notably mobile devices, wearables, automotive infotainment, and other embedded systems with multi-threaded video workflows.
Detection ideas
- Crash dumps or kernel logs showing double-free or memory corruption in video components.
- Unusual thread contention or race-condition signatures during timestamp store operations.
- Repeated video subsystem crashes during playback/recording, or abnormal DSM/driver panics.
- Increased frequency of memory allocator warnings in video drivers.
Mitigation and prioritisation
- Apply vendor security bulletin updates when available; treat as priority 2 unless KEV or EPSS indicates active exploitation (then escalate to priority 1).
- Patch devices firmware/SoC software to fix the race condition; verify integrity before deployment.
- Restrict or segment video-processing components; enforce least-privilege execution for affected modules.
- Enable monitoring for video driver crashes and memory-corruption indicators; disable affected features if patches cannot be applied promptly.
- Plan change-control and testing cycles to validate firmware updates across device families.
