About Qualcomm Qca7005 Firmware
CVE-2026-25293 affects Qualcomm Qca7005 Firmware, a product from Qualcomm. Before acting, confirm where Qualcomm Qca7005 Firmware runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: Buffer overflow due to incorrect authorization in PLC FW
The weakness class is Incorrect Authorization. The permission check exists but gets the answer wrong.
Based on its CVSS vector, the flaw needs local or adjacent access, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.
