CVE-2026-31730 affects the Linux kernel fastrpc component, where a double-free of cctx->remote_heap could occur if INIT_CREATE_STATIC ioctl hits an error path and the rpmsg device is removed. The root cause is that fastrpc_init_create_static_process() frees cctx->remote_heap on the err_map ...

CVE-2026-31734

CVE-2026-31734 (Linux kernel sched_ext) has been fixed. The issue was a false negative where is_bpf_migration_disabled() could be incorrect on systems without CONFIG_PREEMPT_RCU, causing migration_disabled == 1 to be treated as truly migration-disabled even for the current task. The BPF prolog no...

CVE-2026-31735

The CVE-2026-31735 issue affects the Linux kernel IOMMU page table handling. Specifically, when an unmap operation partially overlaps a large or contiguous IOPTE, the invalidation/gather logic could flush only the requested range, causing a short invalidation where part of the unmapped area remai...

CVE-2026-31775

The CVE-2026-31775 issue affects the Linux kernel ALSA ctxfi driver. A refactor caused atc_get_resources() to loop over all DAIOTYP entries, causing SPDIF1 (a special type used only on hw20k1 CTSB073X) to be considered for hw20k2 where it has no definition. This could crash the kernel during DAIO...

CVE-2026-43022

The CVE-2026-43022 issue affects the Linux kernel Bluetooth HCI synchronization path: hci_cmd_sync_queue_once() did not indicate when a queue item already existed, risking resource leaks. The fix changes hci_cmd_sync_queue_once() to return -EEXIST when a queue item already exists and requires upd...

CVE-2026-43031

The CVE concerns the Linux kernel xilinx axienet driver. When a TX packet spans multiple buffer descriptors, the current accounting in axienet_free_tx_chain summing per-BD lengths into an accumulator can lose earlier bytes if the packet completes across different polls, causing BQL to overestimat...

CVE-2026-43041

CVE-2026-43041 concerns the Linux kernel: the irq/qrtr path (qrtr_tx_flow) used a radix_tree that could leak memory when intermediate nodes were linked but a subsequent allocation failed.

CVE-2026-43054

CVE-2026-43054 concerns the Linux kernel SCSI target core (tcm_loop). The vulnerability stems from tcm_loop_target_reset() not draining in-flight commands, which can cause SCSI EH to reuse in-flight scsi_cmnd structures and leak LUN references, potentially hanging configfs LUN unlink. The fix dra...

CVE-2026-43059

CVE-2026-43059 affects the Linux kernel Bluetooth MGMT path. A change introducing mgmt_pending_valid() caused completion handlers to unlink commands from the pending list, which could lead to list corruption and potential memory safety issues. The patch fixes two issues: (1) in mgmt_add_adv_patte...

CVE-2026-43070

The CVE describes a Linux kernel BPF verifier flaw: after a BPF_END (byte swap), dst_reg->id is not reset to 0, which can cause the verifier to propagate learned bounds to a linked register, creating a risk of out-of-bounds memory accesses. The concrete impact is potential privilege/escalation...

CVE-2026-43074

CVE-2026-43074 affects the Linux kernel eventpoll code. The vulnerability arises from ep_free() freeing the eventpoll structure while still in use by another thread, creating a use-after-free (UAF). The fix defers kfree() of the epi->ep struct to an RCU grace period to prevent UAF; multiple so...

CVE-2026-43078

The CVE-2026-43078 entry affects the Linux kernel crypto/af_alg component. A root-cause was an overflow in page reassignment within af_alg_pull_tsgl where the update to support page reallocation wasn’t fully reflected in the loop, allowing one extra page to be reassigned. The vulnerability is des...

CVE-2026-43097

CVE-2026-43097 affects the Linux kernel PCI Hyper-V driver. During error handling in hv_pci_probe, the domain_nr is freed twice: first via pci_bus_release_emul_domain_nr(), and again when the bridge release callback pci_release_host_bridge_dev() runs during cleanup, leading to ida_free on an unal...

CVE-2026-43107

CVE-2026-43107 concerns the Linux kernel xfrm subsystem. The root cause is that xfrm_aevent_msgsize() did not reserve space for XFRMA_IF_ID, causing build_aevent() to fail with -EMSGSIZE and potentially trigger a kernel panic via a malformed netlink interaction when if_id is set. The fix uncondit...

CVE-2026-43139

The CVE-2026-43139 entry concerns the Linux kernel xfrm6 subsystem. The issue arises in xfrm6_get_saddr() which does not check the return value of ipv6_dev_get_saddr(); when ipv6_dev_get_saddr() fails with -EADDRNOTAVAIL, saddr->in6 remains uninitialized and xfrm6_get_saddr() incorrectly retur...

CVE-2026-43140

The CVE-2026-43140 vulnerability affects the Linux kernel HID magicmouse driver. Fake USB devices could present their own report descriptors such that input_mapping() does not call, leaving msc->input NULL and causing a crash later. The issue is resolved by detecting this condition in input_co...

CVE-2026-43143

In the Linux kernel, CVE-2026-43143 fixes a concurrency issue in the multi-function device (mfd) core: access/modification of the mfd_of_node_list was not mutex-protected, risking unsafe list manipulation and potential crashes. The fix adds a mutex to guard this list, reducing crash likelihood. P...

CVE-2026-43153

CVE-2026-43153 affects the Linux kernel’s XFS attribute handling: the function xfs_attr_leaf_hasname has an problematic calling convention that can mishandle buffers. The fix is to open-code xfs_attr_leaf_hasname in callers so each caller of xfs_attr3_leaf_read manages buffer release. The issue i...

CVE-2026-43174

The CVE-2026-43174 issue is in the Linux kernel’s io_uring/zcrx subsystem. Descriptions across multiple sources state that post-open error handling was fixed to avoid releasing the zcrx context before all associated page pools are terminated, addressing improper resource cleanup. The practical im...

CVE-2026-43307

The CVE concerns the Linux kernel iio: accel: adxl380 driver. The interrupt handler can miscalculate FIFO entries because the sensor fills FIFO one sample at a time while batches are read, causing the FIFO status to report a non-multiple of N. This can cause the driver to read more entries than p...

CVE-2026-43319

CVE-2026-43319 affects the Linux kernel spidev driver. The vulnerability stemmed from inverted lock ordering between spi_lock and buf_lock across code paths (write/read use buf_lock then spi_lock; ioctl uses spi_lock then buf_lock), enabling potential deadlocks in multi-threaded access. The fix u...

CVE-2026-43369

Summary (CVE-2026-43369): In the Linux kernel’s drm/amd driver, if GPU initialization fails due to an unsupported hardware block, some IP blocks may have a NULL version pointer. During device cleanup, amdgpu_device_set_pg_state and amdgpu_device_set_cg_state access adev->ip_blocks[i].version w...
