Memory corruption in Qualcomm DSP service buffer allocation

IdentifiersCVE-2025-47354CWE-119

CVE-2025-47354 is a Qualcomm vulnerability described in the provided content as memory corruption while allocating buffers in a DSP service. Based on the available information, the flaw occurs during buffer allocation logic in the DSP service and can lead to memory corruption. The issue is referenced as a high-severity Qualcomm-related vulnerability included in Google’s December 2025 Android Security Bulletin at the 2025-12-05 patch level. No further public technical detail about the exact vulnerable function, affected Qualcomm component version, or trigger path is provided in the supplied content.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation of this memory-corruption flaw could allow an attacker to destabilize the affected DSP service and potentially achieve more serious outcomes depending on exploitability, such as code execution within the vulnerable service context, privilege escalation across component boundaries, or compromise of device functionality tied to the DSP subsystem. However, the supplied content does not provide a vendor-confirmed impact statement beyond classifying the issue as a high-severity Qualcomm vulnerability.

Mitigation

If you can’t patch tonight, do this now.

Where immediate patching is not possible, reduce exposure by limiting use of affected devices to trusted applications and networks, restricting installation of untrusted or unnecessary software, and accelerating OEM/vendor firmware rollout validation. Enterprise defenders should verify that managed Android devices have received the 2025-12-05 patch level or vendor-equivalent update and should track vendor-specific remediation status, since Google patch level alone may not guarantee all Qualcomm fixes are present.

Remediation

Patch, then assume compromise.

Apply the December 2025 Android security updates that include the 2025-12-05 patch level, along with the corresponding Qualcomm/OEM-provided firmware and vendor component updates that address CVE-2025-47354. Because Qualcomm issues may depend on OEM integration schedules, remediation requires ensuring both the Android security patch level and the relevant vendor firmware updates have been deployed on affected devices.
