A Qualcomm chipset vulnerability (CVE-2026-21385) causes memory corruption through improper integer handling during memory allocation, enabling local privilege escalation to kernel level. KEV-listed and patched, this vulnerability affects Qualcomm-based mobile devices and embedded systems, potentially impacting billions of Android devices globally.
5G Fixed Wireless Access Platform Firmware versions up to - contains a vulnerability that allows attackers to cryptographic issue when a VoWiFi call is triggered from UE (CVSS 7.2).
Memory corruption in Qualcomm's PlayReady Trusted Application (TA) occurs when the TA processes crafted commands, and since the vulnerability is reachable only through the local trusted-execution environment it requires an attacker who can already run code on the device at app privilege level. Successful exploitation could corrupt memory within the Trusted Execution Environment and lead to code execution or integrity loss (CWE-131, Incorrect Calculation of Buffer Size), affecting a very broad range of Qualcomm chipsets across mobile, modem, IoT, automotive, compute, and wearable platforms. No public exploit code has been identified and EPSS is negligible (0.09%, 0th percentile), so this is an access-gated issue that matters most to devices that ship and rely on the affected PlayReady TA.
