CVE-2026-89977

CVE-2026-89977 affects the accel/ethosu driver in the Linux kernel . The root cause is a missing error check: devm_platform_ioremap_resource() can return an error pointer when the register resource cannot be mapped, but ethosu_probe() stores the pointer and continues execution until later initial...

CVE-2026-89976

CVE-2026-89976 affects the Linux kernel's accel/ethosu driver (Arm Ethos-U NPU accelerator). In ethosu_ioctl_submit_job(), the done_fence is allocated before buffer handles are validated. On error paths, ethosu_job_err_cleanup() frees the job but leaks the uninitialized fence. Additionally, a sch...

CVE-2026-89974

CVE-2026-89974 is a double free vulnerability in the Linux kernel's nvme-fc (NVMe over Fibre Channel) transport . The fabrics options pointer (ctrl->ctrl.opts) is freed by both nvme_fc_ctrl_free() and nvmf_create_ctrl() when nvme_add_ctrl() fails, after commit 1a9e218195a5 introduced a second ...

CVE-2026-89975

Linux kernel nvme-fabrics contains a memory leak in the DHCHAP secret parsing path. When nvmf_parse_options() validates a dhchap_secret or dhchap_ctrl_secret value and the DHHC-1: representation check fails, the temporary string duplicated by match_strdup() is never assigned to the options struct...

CVE-2026-89973

CVE-2026-89973 affects the nvme-tcp driver in the Linux kernel. The function nvme_tcp_handle_c2h_data() validates a C2HData PDU's command ID and payload presence but does not check the data direction . A malicious or buggy NVMe controller can trigger a kernel warning (WARN_ON_ONCE in _copy_to_ite...

CVE-2026-89972

CVE-2026-89972 is a use-after-free vulnerability in the Linux kernel NVMe subsystem . The error path in nvme_alloc_ns() removes a namespace from the siblings list via list_del_rcu() but fails to call synchronize_srcu() before freeing the namespace struct. Concurrent readers in nvme_find_path() an...

CVE-2026-89971

CVE-2026-89971 affects the Linux kernel NVMe subsystem . The root cause is an insufficient error check in nvme_update_ns_info_block(): it only handles negative errno returns from nvme_query_zone_info(), missing positive NVMe status codes. This causes setup to proceed with zero-initialized zone li...

CVE-2026-89970

CVE-2026-89970 is a use-after-free vulnerability in the Linux kernel NVMe Target (nvmet) authentication subsystem. During Submission Queue (SQ) teardown, nvmet_auth_sq_free() uses cancel_delayed_work() to stop auth_expired_work, but if the work has already started, cancellation does not wait for ...

CVE-2026-89969

CVE-2026-89969 is a critical out-of-bounds write in the Linux kernel's NVMe over TCP target (nvmet-tcp) module. The function nvmet_tcp_try_recv_pdu() reads PDU data into a fixed 128-byte buffer without bounding the payload length against the buffer size. When a header digest has been negotiated a...

CVE-2026-89968

CVE-2026-89968 affects the Linux kernel's NVMe/TCP target (nvmet-tcp). The function nvmet_tcp_handle_h2c_data_pdu() accepts an H2CData PDU without verifying that the target has actually solicited the data via an R2T for that command. A remote host can exploit this by sending an H2CData PDU before...

CVE-2026-89967

CVE-2026-89967 is an out-of-bounds write in the Linux kernel 's mm/migrate_device subsystem. The functions migrate_device_range() and migrate_device_pfns() clear entries following a compound folio to maintain page-granular PFN arrays, but fail to limit writes to the number of slots remaining in t...

CVE-2026-89966

CVE-2026-89966 affects the Linux kernel in the mm/hugetlb_cma subsystem. The root cause is a NULL nodemask dereference in hugetlb_cma_alloc_frozen_folio(): when alloc_buddy_hugetlb_folio_with_mpol() passes a NULL nodemask as a fallback for gigantic (e.g., 1 GB) hugepage allocations, the function ...

CVE-2026-89965

CVE-2026-89965 affects the Linux kernel nvdimm/btt subsystem. The BTT info block's nfree field (number of reserve free blocks) is read from the medium without validation. btt_freelist_init() and btt_rtt_init() size per-lane freelist[] and rtt[] arrays by nfree, but the I/O path indexes them by la...

CVE-2026-89964

CVE-2026-89964 affects the Linux kernel on the parisc architecture, specifically the EISA (Extended Industry Standard Architecture) IRQ setup function eisa_irq_setup(). When an invalid value is supplied via the eisa_irq_edge= kernel command-line parameter (e.g., eisa_irq_edge=16,5), the function ...

CVE-2026-89963

CVE-2026-89963 affects the Linux kernel in the powerpc/kexec_file subsystem. A potential NULL pointer dereference exists in the function kexec_extra_fdt_size_ppc64() : on platforms without any reserved memory regions, get_reserved_memory_ranges() can return 0 while leaving the pointer 'rmem' unal...

CVE-2026-89962

CVE-2026-89962 affects the Linux kernel 's powerpc/kexec_file subsystem. The __merge_memory_ranges() function contains two logic flaws: it compares the current range's start address against the previous element (i-1) instead of the running merged index (idx), and it unconditionally overwrites ran...

CVE-2026-89961

CVE-2026-89961 affects the Linux kernel 's powerpc/mm subsystem, specifically the vmemmap_populate_compound_pages() function. The root cause is a mismatch in how addr_pfn is advanced relative to the loop's addr variable in vmemmap address space. Because each PAGE_SIZE step in addr spans PAGE_SIZE...

CVE-2026-89960

CVE-2026-89960 is a use-after-free in the Linux kernel's s390 vfio-ap (Protected Crypto Accelerator) subsystem. In vfio_ap_mdev_set_kvm(), the kvm->arch.crypto.pqap_hook pointer is set before checking for a conflicting mdev assignment. If another mdev already owns the KVM instance, the functio...

CVE-2026-89959

CVE-2026-89959 is a Linux kernel vulnerability in the s390/vfio-ap subsystem. The vfio_ap_config_remove function incorrectly used bitmap_andnot instead of bitmap_and when clearing bits from the matrix_mdev->matrix.adm bitmap (which tracks control domains assigned to a mediated device). This pr...

CVE-2026-89958

This vulnerability affects the Linux kernel 's s390/vfio-ap driver. The root cause is a NULL pointer dereference : the vfio_ap_on_cfg_changed and vfio_ap_on_scan_complete callback functions acquire the matrix_mdev->kvm->lock mutex without first checking whether matrix_mdev->kvm is NULL. ...
