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.
Transient DOS when a remote device sends an invalid connection request during BT connectable LE scan. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. No vendor patch available.

Local privilege escalation in Qualcomm's DSP service buffer-allocation path affects numerous FastConnect, QMP1000, SM-series, and Snapdragon mobile/wearable platform firmware components. The flaw is a use-after-free (CWE-416) that allows an authenticated local attacker with low privileges-such as a malicious app or compromised unprivileged process able to reach the DSP IPC interface-to corrupt memory and potentially execute code in the DSP context, yielding high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and EPSS is 0.09%, so priority is bounded by the local-only attack vector despite the 7.8 CVSS score.
Memory corruption in Qualcomm chipset firmware (FastConnect, Snapdragon, and associated audio/connectivity chips) allows local attackers with low privileges to execute code or escalate privileges by submitting crafted user buffers to the vulnerable buffer-handling code. The integer overflow (CWE-190) requires on-device execution and an active targeted subsystem; no public exploit code has been identified as of analysis, and the EPSS score is low at 0.09%. Affected firmware includes FastConnect 6200/6700/6900/7800, SG6150(P), SM8750(P), SM8850(P), and WCD/WCN/WSA series.
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.
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.
Transient denial of service in Qualcomm video firmware can be caused when a local attacker with low privileges supplies malformed video packets to the video firmware path, triggering an out-of-bounds read (CWE-126) that affects availability only. The issue affects a broad set of Qualcomm chipsets and platforms enumerated in the vendor advisory, including FastConnect, QCA, Snapdragon, and related firmware families, but exploitation requires local access and crafted packet delivery; there is no remote vector, and the CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H with a base score of 5.5. No public exploit code was identified at time of analysis, CISA KEV does not list this CVE, and EPSS is 0.08%, so overall priority is low-to-moderate despite the wide chipset portfolio.
