Description
In the Linux kernel, the following vulnerability has been resolved: driver: soc: xilinx: fix memory leak in xlnx_add_cb_for_notify_event() The kfree() should be called when memory fails to be allocated for cb_data in xlnx_add_cb_for_notify_event(), otherwise there will be a memory leak, so add kfree() to fix it.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's Xilinx SoC driver. Specifically, when memory allocation for cb_data in the function xlnx_add_cb_for_notify_event() fails, the allocated memory is not freed properly, causing a memory leak. The fix involves adding a call to kfree() to release the memory when allocation fails.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing the system to run out of memory, which may result in crashes or instability.

Mitigation Strategies

Apply the patch or update to the Linux kernel version that includes the fix for the memory leak in the xilinx soc driver, specifically the fix in xlnx_add_cb_for_notify_event() where kfree() is called properly to prevent the leak.
