Description OSIDB Bzimport 2025-12-08 07:10:41 UTC 
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.
