Memory corruption in Qualcomm firmware's Generic Packet Router (GPR) lets a locally present, low-privileged attacker escalate to root-level code execution on a broad range of Snapdragon, FastConnect, QAM/QCA/QCN and related chipsets. Per the CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 7.8), the flaw requires an existing foothold as an unprivileged local process - a malicious or compromised app, for example - which then routes an oversized data packet through the GPR path that bridges user and root/kernel contexts, triggering a CWE-190 integer overflow and full compromise of confidentiality, integrity and availability. It is not remotely reachable, and no public exploit code or confirmed active exploitation was identified at time of analysis; Qualcomm published the issue in its December 2025 security bulletin for OEM distribution.
Memory corruption in Qualcomm firmware - an out-of-bounds write (CWE-787) triggered when the reboot code path parses a malformed license file - can lead to code execution or denial of service in the affected subsystem. The flaw is local and privilege-dependent: per the CVSS vector (AV:L/PR:L/UI:N) the attacker must already hold a local foothold with low privileges on the device and must be able to place or influence the license file before a reboot, so it is not a remote or default-unauthenticated condition. No public exploit code has been identified at time of analysis (EPSS is 0.09%, percentile-based score negligible), and there is no confirmed active exploitation.
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.
