    Changed Description In the Linux kernel, the following vulnerability has been resolved: ubifs: dirty_cow_znode: Fix memleak in error handling path Following process will cause a memleak for copied up znode: dirty_cow_znode zn = copy_znode(c, znode); err = insert_old_idx(c, zbr->lnum, zbr->offs); if (unlikely(err)) return ERR_PTR(err); // No one refers to zn. Fix it by adding copied znode back to tnc, then it will be freed by ubifs_destroy_tnc_subtree() while closing tnc. Fetch a reproducer in [Link].
