Memory corruption while processing identity credential operations in the trusted application. [CVSS 7.8 HIGH]
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 while accessing a buffer during IOCTL processing. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Memory corruption while performing encryption and decryption commands. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Memory corruption in Qualcomm firmware components (FastConnect 6700/6900/7800, QCC2072, Snapdragon 8cx/7c+ Gen 3 compute platforms, and WCD/WSA audio codecs) allows a local authenticated attacker to trigger an out-of-bounds write via crafted IOCTL remote procedure calls, potentially leading to code execution or privilege escalation. No public exploit code or active exploitation has been identified; EPSS is 0.09%, indicating low predicted exploit likelihood. The primary limiting factor is the need for local access with low privileges (PR:L) to invoke the vulnerable IOCTL interface.
Memory corruption in the image-encoding completion event handler of multiple Qualcomm chipset firmware images allows an attacker who already holds local, low-privilege code execution on the device to trigger a buffer overflow and achieve high integrity and confidentiality impact (CVSS 7.8, AV:L/AC:L/PR:L/UI:N). The affected platforms span FastConnect 6700/6900/7800 connectivity chips, QCC2072, QCM/QCS 5430 and 6490, SC8380XP, the VC3 video collaboration platform, WCD/WSA audio codecs, and Snapdragon 8cx Gen 3 / 7c Gen 3 compute platforms. There is no indication of confirmed active exploitation (not in CISA KEV) and no public exploit code identified at time of analysis; EPSS is negligible at 0.09% (0th percentile), consistent with a local-only precondition. Vendor-released fixes are documented in Qualcomm's October 2025 security bulletin and are distributed through device OEMs.
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.
Local attackers with low privileges can trigger a transient denial-of-service (DoS) in Qualcomm FastConnect firmware (and other listed Qualcomm chipsets) by invoking a crafted IOCTL call for image encoding, leading to a temporary device reset. The flaw is not remotely exploitable and requires existing code execution on the device; it affects availability only, with no confidentiality or integrity impact, and recovery is automatic. With an EPSS score of 0.08% and no public exploit identified, this is a low-priority issue.

Use-after-free memory corruption vulnerability in IOCTL command processing that occurs when buffers in write loopback mode are accessed after being freed. This local privilege escalation affects authenticated users (PR:L) on affected systems and can enable attackers to achieve confidentiality, integrity, and availability compromise (C:H/I:H/A:H). The vulnerability requires local access and low complexity exploitation, making it a significant risk for multi-user systems or systems where local code execution is possible.
Memory corruption vulnerability in Qualcomm's Virtual Machine (VM) attachment mechanism that occurs when the Host Linux OS (HLOS) retains access to a VM during attachment operations. This local privilege escalation vulnerability affects Qualcomm System-on-Chip (SoC) implementations and allows a local attacker with user-level privileges to achieve code execution with full system compromise (confidentiality, integrity, and availability impact). The vulnerability has not been reported as actively exploited in the KEV catalog, but the high CVSS score (7.8) and local attack vector indicate significant real-world risk for deployed Qualcomm-based devices.
