Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: ext4: fix potential memory leak in ext4_fc_record_regions() As krealloc may return NULL, in this case 'state->fc_regions' may not be freed by krealloc, but 'state->fc_regions' already set NULL. Then will lead to 'state->fc_regions' memory leak.
