    platform/chrome: sensorhub: Fix memory overread in ring handler

    In the Linux kernel, the following vulnerability has been resolved: platform/chrome: sensorhub: Fix memory overread in ring handler `max_response` and `sensor_num` are read from different EC commands: - `max_response` is from cros_ec_get_proto_info(). ec_dev->max_response = info->max_response_packet_size - sizeof(struct ec_host_response); - `sensor_num` is from cros_ec_get_sensor_count(). sensor_num = cros_ec_get_sensor_count(ec); With a malfunctioning EC firmware, it is possible that the `msg->insize` (i.e., `fifo_info_length` in the context) could be clamped in cros_ec_cmd_xfer() because `msg

    hwrng: core - fix rng list on registration error

    In the Linux kernel, the following vulnerability has been resolved: hwrng: core - fix rng list on registration error hwrng_register(rng) does the following: 1. Checks if rng has name and read methods set 2. Checks if the name already exists 3. Adds rng to global rng_list 4. May try to set rng to current_rng If step 4 fails, it returns an error. However, it does not remove the rng from rng_list, causing a dangling reference which can result in use-after-free if the caller frees rng, since registration failed. Add a list_del_init() cleanup step.

    crypto: qat - cancel work on re-enable SR-IOV timeout

    In the Linux kernel, the following vulnerability has been resolved: crypto: qat - cancel work on re-enable SR-IOV timeout The QAT reset worker queues SR-IOV reenable work using a work_struct and completion embedded in an on-stack adf_sriov_dev_data. If the completion wait times out, the reset worker can return while device_sriov_wq still holds or executes the stack-backed work item. Cancel the work on the device_sriov_wq on timeout before the stack frame unwinds.

    crypto: atmel-ecc - reject hardware ECDH without a public key

    In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-ecc - reject hardware ECDH without a public key The hardware ECDH path in atmel_ecdh_compute_shared_secret() uses the private key stored in the device. However, the public key is cached only after atmel_ecdh_set_secret() successfully generated that private key for the current tfm. atmel_ecdh_generate_public_key() already rejects requests when no public key is cached. Add the same check to atmel_ecdh_compute_shared_secret() to prevent the device from using a private key that was not generated for the current tfm.

    crypto: atmel-sha204a - fix heap info leak on I2C transfer failure

    In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-sha204a - fix heap info leak on I2C transfer failure The nonblocking RNG path allocates a work_data structure to track the state of an in-flight asynchronous I2C request. This pointer is stored in rng->priv and later consumed by the read path once the transaction completes. If the underlying I2C transfer fails, the completion callback is invoked with a non-zero status. In this case, the allocated work_data is not usable for producing RNG output and must not remain associated with the hwrng state. Previously, the failure path only logged a warning but left th

    crypto: sa2ul - stop probe if context pool creation fails

    In the Linux kernel, the following vulnerability has been resolved: crypto: sa2ul - stop probe if context pool creation fails sa_ul_probe() calls sa_init_mem() to create the DMA pool used for security context buffers, but ignores its return value. If pool creation fails, probe still continues with DMA setup, algorithm registration and child population even though later request setup depends on that pool. Stop probing when sa_init_mem() fails, and route that failure to the PM cleanup path without attempting to destroy an uncreated DMA pool.

    crypto: rk3288 - fail ahash requests on HASH idle timeout

    In the Linux kernel, the following vulnerability has been resolved: crypto: rk3288 - fail ahash requests on HASH idle timeout rk_hash_run() waits for RK_CRYPTO_HASH_STS to become idle after the final DMA transfer, but ignores the poll result. If the hash engine never becomes idle, the driver still reads the digest registers and finalizes the request with the previous success value. Store the poll result and finalize the request with the timeout error before reading the digest registers.

    crypto: keembay - Fix AEAD unregister count in error path

    In the Linux kernel, the following vulnerability has been resolved: crypto: keembay - Fix AEAD unregister count in error path register_aes_algs() registers the AEAD algorithms before registering the skcipher algorithms. If skcipher registration fails, the function unwinds the earlier AEAD registration with crypto_engine_unregister_aeads(), but it passes ARRAY_SIZE(algs), which is the skcipher table size. Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper iterates over the same table that was registered. Also clarify the nearby comment: the crypto registration helpers clean up algorithms registered within the same

    nvme-apple: Use acquire/release for queue enabled state

    In the Linux kernel, the following vulnerability has been resolved: nvme-apple: Use acquire/release for queue enabled state apple_nvme_init_queue() initializes queue state and then marks the queue enabled. The interrupt and request paths check enabled before using that queue state. The old wmb() after WRITE_ONCE(enabled, true) does not publish the earlier initialization before enabled becomes visible. Use a release store when enabling the queue and acquire loads when testing it. Although the shutdown-side enabled accesses are not used for publishing queue initialization, use helpers for them as well for consistency.

    nvmet-rdma: fix response resource leak on queue teardown

    In the Linux kernel, the following vulnerability has been resolved: nvmet-rdma: fix response resource leak on queue teardown When an nvme target with rdma transport is removed while I/Os are in flight, a response can be posted but its send completion is never delivered before the connection is torn down. As a result nvmet_rdma_send_done() and nvmet_rdma_release_rsp() are never called for the response, and this leaks the allocated RDMA read/write context and request SGLs. These leaks are recreated by running blktests nvme/061 with the rdma transport and the siw driver. Kernel kmemleak feature reports them as follows: unreferenced object

    cgroup/cpuset: Make nr_deadline_tasks an atomic_t

    In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Make nr_deadline_tasks an atomic_t The nr_deadline_tasks variable in the cpuset structure was introduced by commit 6c24849f5515 ("sched/cpuset: Keep track of SCHED_DEADLINE task in cpusets"). It is reported by sashiko [1] that nr_deadline_tasks can currently be modified by inc_dl_tasks_cs() under rq->lock and by cpuset_attach() under cpuset_mutex. So if both updates happen simultaneously, the nr_deadline_tasks variable can be corrupted leading to incorrect operations down the road. Fix that by changing its type to atomic_t so that nr_deadline_tasks are alway

    wifi: mac80211_hwsim: avoid NULL skb in stop queue drain

    In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211_hwsim: avoid NULL skb in stop queue drain mac80211_hwsim_stop() drops any frames left in data->pending. The loop currently checks skb_queue_empty() and then dequeues separately. That split is racy with TX status handling, which can remove a pending frame under the queue lock. If the last entry is removed after the empty check, skb_dequeue() returns NULL and the stop path passes that NULL skb to ieee80211_free_txskb(). Use skb_dequeue() as the loop condition instead. The dequeue result is the object that stop owns and frees, and a concurrent status completio

    bpf: Reject MEM_ALLOC BTF accesses past object bounds

    In the Linux kernel, the following vulnerability has been resolved: bpf: Reject MEM_ALLOC BTF accesses past object bounds BTF struct walks relax the struct-size check for accesses through a trailing flexible array. That is valid for ordinary BTF type walking, but PTR_TO_BTF_ID | MEM_ALLOC values point to objects allocated with the static BTF type size. When walking a MEM_ALLOC object, reject the access before applying the flexible-array relaxation if the access range extends past the struct size. Apply the same policy to struct ID matching so kfunc and kptr type checks do not walk past the allocated object bounds either.

Move the call until later to avoid an error pointer dereference of "priv->zone". The driver works differently depending on if we are using OF thermal or not. We use thermal_add_hwmon_sysfs() if we are using OF thermal and call thermal_zone_device_enable() if not. We can share same error check for if either of these fail. Moving the thermal_zone_device_enable() call is a bit cleaner as wel
