CVE-2025-47385 is a memory corruption vulnerability that arises when accessing the trusted execution environment without proper privilege checks. It affects components in Qualcomm products, as detailed in the vendor's March 2026 security bulletin. The issue carries a CVSS v3.1 base score of 7.8, with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, and is classified under CWE-1262. The vulnerability was published on 2026-03-02.
A local attacker with low privileges can exploit CVE-2025-47385 with low attack complexity and no user interaction. Exploitation enables high-impact consequences, including unauthorized access to confidential data, modification of system integrity, and disruption of availability through memory corruption in the trusted execution environment.
Qualcomm's security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/march-2026-bulletin.html provides details on affected products, patches, and mitigation recommendations for addressing this vulnerability.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Enforcing approved authorizations for logical access directly stops unauthorized software from reaching memory-mapped registers.
Least-privilege assignment restricts which processes may access hardware registers, reducing the chance of improper interface exposure.

Security testing can discover improper register access but does not prevent it at runtime.
Privileged utility programs may touch registers, so the control partially mitigates misuse.
Privileged access rights directly restrict who can read/write hardware registers.
Secure architecture principles require proper hardware register access controls by design.
Secure coding practices prevent unauthorized register access in firmware and drivers.
Information access restriction explicitly limits software access to memory-mapped register interfaces.
