CVE-2023-33107
Memory Safety in Qualcomm 315 5G Iot Modem Firmware
Raw vector
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-33107 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Qualcomm 315 5G Iot Modem Firmware. Its CVSS base score is 8.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique LSA Secrets (T1003.004); ranked in the top 46% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-33107 is a memory corruption vulnerability, tracked under CWE-190, that occurs in the Graphics Linux component when assigning a shared virtual memory region during an IOCTL call. The flaw affects Qualcomm platforms that incorporate this Linux graphics driver code and carries a CVSS 3.1 base score of 8.4, reflecting high impact on confidentiality, integrity, and availability.
An attacker with local access and no privileges can invoke the affected IOCTL to trigger the corruption, enabling arbitrary code execution or denial of service within the graphics subsystem. Because the attack vector is local and requires no user interaction or elevated permissions, the issue can be reached from an untrusted application or compromised process running on the device.
Qualcomm’s December 2023 security bulletin addresses the issue with patches for impacted chipsets and software releases. The vulnerability also appears in CISA’s catalog of known exploited vulnerabilities, confirming observed in-the-wild use; the current EPSS score of 0.004 remains low and shows no material upward trajectory.
