https://notcve.org/view.php?id=CVE-2024-53171
27 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: ubifs: authentication: Fix use-after-free in ubifs_tnc_end_commit After an insertion in TNC, the tree might split and cause a node to change its `znode->parent`. A further deletion of other nodes in the tree (which also could free the nodes), the aforementioned node's `znode->cparent` could still point to a freed node. This `znode->cparent` may not be updated when getting nodes to commit in `ubifs_tnc_start_commit()`. This could then trig... • https://git.kernel.org/stable/c/16a26b20d2afd0cf063816725b45b12e78d5bb31 •
