CVE-2022-50438
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2022-50438 affects the Linux kernel and involves a memory leak vulnerability in the net/hinic subsystem. The issue occurs when reading the function table, specifically when the input parameter idx meets the expected case option in hinicdbggetfunctable(), where read_data is not properly released (NVD, Ubuntu).

Technical details

The vulnerability is present in the hinicdbggetfunctable() function of the Linux kernel's networking subsystem. When the input parameter idx matches certain conditions, the read_data resource is not properly deallocated, leading to a memory leak condition (NVD).

Impact

The memory leak vulnerability can lead to resource exhaustion over time as memory is not properly freed, potentially affecting system stability and performance (NVD).

Mitigation and workarounds

The issue has been fixed in various Linux kernel versions. Ubuntu has released patches for affected systems, particularly in version 5.15.0-60.66~20.04.1 for linux-hwe-5.15 and other kernel variants (Ubuntu).
