CVE-2023-53195:
Linux Kernel vulnerability analysis and mitigation
Overview
A memory leak vulnerability was identified in the Linux kernel's mlxsw minimal driver (CVE-2023-53195). The issue occurs in the mlxswmlinecards_init() function where the line cards array is not properly freed in the error path, potentially leading to memory leaks (NVD).
Technical details
The vulnerability exists in the Linux kernel's mlxsw minimal driver implementation. Specifically, the issue occurs when the line cards array is not freed in the error path of mlxswmlinecardsinit(), which can result in memory leaks. The fix involves freeing the array in the error path, making it consistent with the mlxswmlinecardsfini() implementation (NVD).
Impact
The vulnerability can lead to memory leaks in the affected Linux kernel systems, potentially causing resource exhaustion over time (NVD).
Mitigation and workarounds
The vulnerability has been resolved in the Linux kernel through a patch that properly frees the line cards array in the error path of mlxswmlinecardsinit(). The fix makes the error path identical to mlxswmlinecardsfini() (NVD).
