Analysis

Impact

Memory corruption occurs when the fingerprint trusted application processes malformed request parameters. The vulnerability can lead to overwritten memory and possible arbitrary code execution or denial of services. This weakness is a classic buffer overflow, classified as CWE‑120.

Affected Systems

The affected product is Qualcomm’s Snapdragon platform, specifically the fingerprint trusted application component. No specific firmware or build versions are listed, so any Snapdragon device that includes the unpatched fingerprint TA is potentially impacted.

Risk and Exploitability

The CVSS score of 7.8 indicates a high severity vulnerability. EPSS data is not available, making exploitation probability unclear, and the vulnerability is not listed in the CISA KEV catalogue. Attack vectors are not explicitly stated in the advisory; however, the likely attack path involves an attacker supplying crafted data to the fingerprint TA, which may be local or rely on elevated privileges. Given the lack of mitigation details, the risk remains elevated pending a patch.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Update the Snapdragon firmware or operating system to the latest version that includes the vendor‑supplied fix for the fingerprint trusted application.
If an immediate update is unavailable, restrict access to the fingerprint TA and enforce strict input validation or sandboxing to limit the impact of malformed requests.
Enable any available memory protection mechanisms (e.g., stack canaries, address space layout randomization) to reduce the likelihood that an overflow will lead to code execution.
