Published: May 28, 2026


Vulnerability identifier: #VU132601
CSH Severity: Low
CVSS v4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-45883
CWE-ID: CWE-772
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a resource leak in sca3000_probe() when handling device initialization failures. A local user can trigger initialization that causes iio_device_register() to fail to cause a denial of service.
