Background
The Kernel is a crucial component of the Linux operating system that manages system resources and facilitates communication between hardware and software. It provides essential functionalities for the proper functioning of the system. The imu_fmt module in the media staging/intel-ipu3 subsystem is responsible for handling image format operations for Intel IPUs (Image Processing Units).
Vulnerability Detail
The vulnerability identified in the imu_fmt module of the Kernel is a memory leak issue. A memory leak occurs when a program fails to release memory that is no longer needed, leading to a gradual depletion of available memory resources. In this case, the imu_fmt module fails to release memory, resulting in a continuous accumulation of memory usage. If left unaddressed, this can eventually lead to system instability, performance degradation, and potential denial-of-service scenarios.
How To Fix
No fixed version is published for this vulnerability.
To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.4.118 or later. The fix for this issue was implemented in commit ff792ae52005c85a2d829c153e08d99a356e007d. Updating to the latest version will ensure that the memory leak in imu_fmt is resolved.
