AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A resource leak vulnerability in the Linux kernel's iio sca3000 driver was fixed. The issue involved the failure to release the spi->irq resource when iio_device_register() failed during device probing. This could lead to resource exhaustion affecting system availability.

The Linux kernel's iio sca3000 driver had a resource leak in the sca3000_probe() function. Specifically, the interrupt request line (spi->irq) obtained via request_threaded_irq() was not released if iio_device_register() failed. The fix added a return value check for iio_device_register() and ensured that on failure, control jumps to a common error handler to release allocated resources properly. This vulnerability is tracked as CVE-2026-45883 and is categorized under CWE-401 (Improper Release of Memory or Resource).

In the Linux kernel, the following vulnerability has been resolved: iio: sca3000: Fix a resource leak in sca3000_probe() spi->irq from request_threaded_irq() not released when iio_device_register() fails. Add an return value check and jump to a common error handler when iio_device_register() fails.

CVE-2026-45883 is a resource leak vulnerability in the Linux kernel's Industrial I/O (iio) subsystem, specifically in the sca3000 driver. The flaw occurs in the sca3000_probe() function where the interrupt request (spi->irq) obtained via request_threaded_irq() is not released if iio_device_register() fails. The fix adds a return value check and error handling to ensure proper resource cleanup on failure. This vulnerability was resolved in linux-azure kernel versions starting from 5.15.0-1112.119~20.04.1 and later. The issue is part of a broader set of Linux kernel security fixes released by Ubuntu in July 2026.
