Description
In the Linux kernel, the following vulnerability has been resolved: ext4: fix potential memory leak in ext4_fc_record_modified_inode() As krealloc may return NULL, in this case 'state->fc_modified_inodes' may not be freed by krealloc, but 'state->fc_modified_inodes' already set NULL. Then will lead to 'state->fc_modified_inodes' memory leak.

Executive Summary

This vulnerability is a potential memory leak in the Linux kernel's ext4 filesystem code. Specifically, in the function ext4_fc_record_modified_inode(), when the krealloc function returns NULL, the memory pointed to by state->fc_modified_inodes may not be freed properly because state->fc_modified_inodes is already set to NULL. This leads to a memory leak.

Impact Analysis

The impact of this vulnerability is a potential memory leak in the Linux kernel, which could lead to increased memory usage and possibly degrade system performance or stability over time if exploited or triggered repeatedly.
