Qualcomm Adreno GPU drivers in Chrome contain a use-after-free vulnerability (CVE-2025-27038, CVSS 7.5) enabling memory corruption during graphics rendering. KEV-listed, this vulnerability can be triggered through Chrome on Android devices with Qualcomm chipsets, providing a kernel-level exploitation path from web content.
Cryptographic issue when a Trusted Zone with outdated code is triggered by a HLOS providing incorrect input. [CVSS 7.1 HIGH]
Memory corruption occurs when a secure application is launched on a device with insufficient memory. [CVSS 7.8 HIGH]
Memory corruption when copying overlapping buffers during memory operations due to incorrect offset calculations. [CVSS 7.8 HIGH]
Memory corruption while passing pages to DSP with an unaligned starting address. [CVSS 7.8 HIGH]
Memory corruption while processing identity credential operations in the trusted application. [CVSS 7.8 HIGH]
Memory corruption while processing a secure logging command in the trusted application. [CVSS 7.8 HIGH]
Cryptographic issue may occur while encrypting license data. [CVSS 8.4 HIGH]
Memory corruption while deinitializing a HDCP session. [CVSS 7.8 HIGH]
Memory corruption while processing shared command buffer packet between camera userspace and kernel. [CVSS 6.7 MEDIUM]
Memory corruption while handling buffer mapping operations in the cryptographic driver. [CVSS 6.6 MEDIUM]
Information disclosure while processing a firmware event. [CVSS 6.1 MEDIUM]
Transient DOS while parsing video packets received from the video firmware. [CVSS 5.5 MEDIUM]
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.
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 due to global buffer overflow when a test command uses an invalid payload type. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
