CVE-2026-72193

CVE-2026-72193 concerns the in-tree ntfs3 kernel driver. A crafted NTFS3 disk image could trigger an in-kernel infinite loop during mount via a corrupted RESTART_TABLE free-chain, hanging the mounting thread and potentially invoking the soft-lockup watchdog on multi-CPU systems. The vulnerability...

CVE-2026-72192

The CVE-2026-72192 issue affects the Linux kernel ntfs3 code. Specifically, indx_insert_into_root before hdr_insert_head can overrun a kmalloc(index_block_size) when shrinking root->index_block_size (e.g., to 512) after the root is populated. A crafted NTFS image triggers a memcpy of attacker-...
