Background
The Linux kernel is the core component of the Linux operating system, responsible for managing hardware resources and providing essential services to applications. It is widely used in various distributions, including Debian. The kernel's stability and security are paramount, as vulnerabilities can lead to system crashes, data loss, or unauthorized access. This specific vulnerability affects the 'linux' package in Debian versions 13 and 14, highlighting the importance of timely updates and patches.
Vulnerability Detail
In the Linux kernel, a vulnerability has been identified in the iio subsystem, specifically within the gts-helper functionality. The issue arises in the iio_gts_build_avail_scale_table() function, where memory allocated for per_time_scales and per_time_gains may not be properly freed if certain conditions are met. If the kcalloc function fails during the allocation process, the error handling does not adequately release previously allocated memory, leading to memory leaks. This can result in increased memory consumption over time, potentially affecting system performance and stability.
