"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: fail recovery on a committed log item with no regions\n\nIf the first op of a transaction is a bare transaction header\n(len == sizeof(struct xfs_trans_header)), xlog_recover_add_to_trans()\nadds an item but no region, leaving it on r_itemq with ri_cnt == 0 and\nri_buf == NULL.\n\nThe header can be split across op records, so later ops may still add\nregions; the item is only invalid if the transaction commits with none.\nThe runtime commit path never emits such a transaction, so this only\nhappens on a crafted log. It came from an AI-assisted code audit of the\nrecovery parser.\n\nxlog_recover_reorder_trans() calls ITEM_TYPE() on the item, which reads\n*(unsigned short *)item->ri_buf[0].iov_base and faults on the NULL\nri_buf. Reject it there, before the commit handlers that also read\nri_buf[0].\n\n KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n RIP: 0010:xlog_recover_reorder_trans (fs/xfs/xfs_log_recover.c:1836)\n xlog_recover_commit_trans (fs/xfs/xfs_log_recover.c:2043)\n xlog_recover_process_data (fs/xfs/xfs_log_recover.c:2501)\n xlog_do_recovery_pass (fs/xfs/xfs_log_recover.c:3244)\n xlog_recover (fs/xfs/xfs_log_recover.c:3493)\n xfs_log_mount (fs/xfs/xfs_log.c:618)\n xfs_mountfs (fs/xfs/xfs_mount.c:1034)\n xfs_fs_fill_super (fs/xfs/xfs_super.c:1938)\n vfs_get_tree (fs/super.c:1695)\n path_mount (fs/namespace.c:4161)\n __x64_sys_mount (fs/namespace.c:4367)"
