Sep 17, 2026In the Linux kernel, the following vulnerability has been resolved: ocfs2/cluster: keep heartbeat local node stable o2nm_node_local_store() handles local=0 byCVE-2026-90322 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: ocfs2/cluster: keep heartbeat local node stable o2nm_node_local_store() handles local=0 by stopping o2net and setting cl_local_node to O2NM_INVALID_NODE_NUM, but it leaves cl_has_local set. That stale state makes o2nm_this_node() return 255, blocks a later local=1 attempt with -EBUSY, and can feed 255 to heartbeat users that call o2nm_this_node() dynamically. Clearing cl_has_local is required when the local node is reset. But heartbeat threads can still be running at that point. They pin the local node config item at startup, yet o2hb_do_disk_heartbeat() and thread teardown re-read o2nm_this_node() for the local slot and for o2nm_undepend_this_node(). Once local=0 has cleared the live local-node state, those dynamic reads return O2NM_MAX_NODES, which is also the invalid node number 255. Store the local node number in the heartbeat region when the region starts. Use that stable node for heartbeat slot writes/checks, negotiation messages, and the final configfs undepend. Stop the heartbeat loop when the current local node no longer matches the stored node, and clear cl_has_local together with cl_local_node

Sep 17, 2026In the Linux kernel, the following vulnerability has been resolved: ocfs2: synchronize heartbeat callbacks with o2net teardown Patch series "ocfs2: harden heaCVE-2026-90302 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: ocfs2: synchronize heartbeat callbacks with o2net teardown Patch series "ocfs2: harden heartbeat teardown races". This series fixes two OCFS2 heartbeat/o2net teardown races found by KASAN. This patch (of 2): Heartbeat callbacks stay registered while configfs local-node teardown enters o2net_stop_listening(). A node-down event can still run through o2net_disconnect_node() and o2net_set_nn_state() while teardown is destroying o2net_wq, so the later queue/flush operations can hit a dead workqueue.

In the Linux kernel, the following vulnerability has been resolved: ocfs2: o2hb: quiesce negotiate handlers and timeout work Heartbeat regions publish struct o2hb_region as the private data for the NEGO_TIMEOUT and NEGO_APPROVE o2net handlers as soon as make_item() creates the configfs region. The approve handler can call o2hb_arm_timeout(), so a peer can touch the region timeout work before dev_store() has finished building the heartbeat runtime, or after teardown has started to shut that runtime back down. The final configfs put also has to keep reg alive until the last in-flight o2net callback drops its handler reference. o2net_unregister_handler_list() blocks future handler lookups, but it does not wait for sc_rx_work that already passed o2net_handler_get(). That drain needs to cover local listener teardown as well, where the o2net ordered workqueue may already be inside destroy_workqueue(). Fix the lifetime rule in both directions. Initialize the region delayed works before publishing reg through the o2net handler table, keep new or stopping regions non-armable with hr_stopping, and quiesce both delayed works on failed-start and teardown paths even when no heartbeat th

Aug 22, 2026In the Linux kernel, the following vulnerability has been resolved: sctp: clear control chunk transport if it is being removed sctp_make_heartbeat_ack() cacheCVE-2026-74688 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Critical 9.8
In the Linux kernel, the following vulnerability has been resolved: sctp: clear control chunk transport if it is being removed sctp_make_heartbeat_ack() caches the destination transport in chunk->transport without taking a reference. When src_out_of_asoc_ok is enabled, the HEARTBEAT ACK may remain queued on control_chunk_list instead of being transmitted immediately. If the peer transport is removed while the chunk is still queued, sctp_assoc_rm_peer() drops the transport and schedules it for RCU freeing, but only clears cached transport pointers in out_chunk_list. The queued control chunk therefore retains a dangling transport pointer. Once an ASCONF_ACK clears the suppression and the queued control chunk is transmitted, SCTP dereferences the stale transport pointer, leading to a use-after-free. Fix this by also clearing chunk->transport for queued control chunks in control_chunk_list when removing the transport.

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: fix refcount underflow in intel_engine_park_heartbeat A use-after-free / refcount underflow is possible when the heartbeat worker and intel_engine_park_heartbeat() race to release the same engine->heartbeat.systole request. The heartbeat worker reads engine->heartbeat.systole and calls i915_request_put() on it when the request is complete, but clears the pointer in a separate, non-atomic step. Concurrently, a request retirement on another CPU can drop the engine wakeref to zero, triggering __engine_park() -> intel_engine_park_heartbeat(). If the heartbeat timer is pending at that point, cancel_delayed_work() returns true and intel_engine_park_heartbeat() reads the stale non-NULL systole pointer and calls i915_request_put() on it again, causing a refcount underflow: ``` <4> [487.221889] Workqueue: i915-unordered engine_retire [i915] <4> [487.222640] RIP: 0010:refcount_warn_saturate+0x68/0xb0 ... <4> [487.222707] Call Trace: <4> [487.222711] <TASK> <4> [487.222716] intel_engine_park_heartbeat.part.0+0x6f/0x80 [i915] <4> [487.223115] intel_engine_park_heartbeat+0x25/0x40 [i915] <4> [487.223566] __

In the Linux kernel, the following vulnerability has been resolved: octeon_ep: Fix host hang issue during device reboot When the host loses heartbeat messages from the device, the driver calls the device-specific ndo_stop function, which frees the resources. If the driver is unloaded in this scenario, it calls ndo_stop again, attempting to free resources that have already been freed, leading to a host hang issue. To resolve this, dev_close should be called instead of the device-specific stop function.dev_close internally calls ndo_stop to stop the network interface and performs additional cleanup tasks. During the driver unload process, if the device is already down, ndo_stop is not called.
