"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2/cluster: keep heartbeat local node stable\n\no2nm_node_local_store() handles local=0 by stopping o2net and setting\ncl_local_node to O2NM_INVALID_NODE_NUM, but it leaves cl_has_local set. \nThat stale state makes o2nm_this_node() return 255, blocks a later local=1\nattempt with -EBUSY, and can feed 255 to heartbeat users that call\no2nm_this_node() dynamically.\n\nClearing cl_has_local is required when the local node is reset. But\nheartbeat threads can still be running at that point. They pin the local\nnode config item at startup, yet o2hb_do_disk_heartbeat() and thread\nteardown re-read o2nm_this_node() for the local slot and for\no2nm_undepend_this_node(). Once local=0 has cleared the live local-node\nstate, those dynamic reads return O2NM_MAX_NODES, which is also the\ninvalid node number 255.\n\nStore the local node number in the heartbeat region when the region\nstarts. Use that stable node for heartbeat slot writes/checks,\nnegotiation messages, and the final configfs undepend. Stop the heartbeat\nloop when the current local node no longer matches the stored node, and\nclear cl_has_local together with cl_local_node in the local=0 path so\nnodemanager state matches node removal.\n\nValidation reproduced this kernel report:\nKASAN slab-out-of-bounds in o2hb_do_disk_heartbeat+0x372/0xb30\nRIP: 0010:memset+0xf/0x20\nRead of size 8\nCall trace:\n dump_stack_lvl+0x66/0xa0\n print_report+0xd0/0x630\n o2hb_do_disk_heartbeat+0x372/0xb30 (fs/ocfs2/cluster/heartbeat.c:1079)\n srso_alias_return_thunk+0x5/0xfbef5\n __virt_addr_valid+0x188/0x2f0\n kasan_report+0xe4/0x120\n o2hb_do_disk_heartbeat+0x5/0xb30 (fs/ocfs2/cluster/heartbeat.c:1079)\n o2hb_thread+0x14e/0x770\n kthread_affine_node+0x139/0x180\n lockdep_hardirqs_on_prepare+0xda/0x190\n trace_hardirqs_on+0x18/0x130\n kthread+0x19d/0x1e0\n ret_from_fork+0x37a/0x4d0\n __switch_to+0x2d5/0x6f0\n ret_from_fork_asm+0x1a/0x30"
