CVE-2026-74486

The CVE-2026-74486 entry describes a Linux kernel vulnerability in binfmt_misc where load_misc_binary() clones the interpreter file and denies write access with exe_file_deny_write_access(), while the exec path later calls exe_file_allow_write_access(). This mismatch can cause repeated write-deni...

CVE-2026-74484

CVE-2026-74484 concerns the Linux kernel’s binfmt_misc feature: an entry registered with the character 'F' can cause the interpreter to pin itself, preventing proper unregistration and leading to a DoS with leaked resources (including user namespaces). The issue arises when the interpreter’s file...

CVE-2026-74485

Summary of CVE-2026-74485 (binfmt_misc delimiter issue) : In the Linux kernel, a vulnerability in binfmt_misc allowed a crafted registration string to cause an out-of-bounds read when the delimiter chosen by the user was itself a flag character (one of P, O, C, F). The padding after create_entry(...

CVE-2026-74482

CVE-2026-74482 — Linux kernel (mm/huge_memory) . The issue arises during THP folio splitting in mm/huge_memory.c: __folio_split dereferences the mapping after the split while folios are still frozen/locked, and calls remap_page() and shmem_uncharge() before unlocking the after-split folios. This ...

CVE-2026-74483

CVE-2026-74483 affects the Linux kernel: binfmt_misc may leak a user namespace across mounts when bm_fill_super() fails. The root cause is improper ownership transfer of the user namespace through s_fs_info leading to a leak, which is mitigated by dropping the reference in kill_sb() so the namesp...

CVE-2026-74481

The CVE-2026-74481 entry describes a Linux kernel UAF/GPF during PM suspend caused by page_reporting work being scheduled on the non-freezable system_wq. Child devices (e.g., virtio_balloon) delete virtqueues as part of suspend, but page_reporting_process could still run, triggering virtballoon_f...

CVE-2026-74480

CVE-2026-74480 affects the Linux kernel networking bridge code. The fast-leave path in br_multicast_leave_group() can dereference a stale mp->ports entry after br_multicast_del_pg() removes a port group, enabling a scenario where multiple port groups for the same port/group with different sour...

CVE-2026-74479

CVE-2026-74479 — Linux kernel pktgen use-after-free : Multiple sources describe a race in proc entry handling inside pktgen where pktgen_change_name() mutates pkt_dev->entry under t->if_lock while pktgen_remove_device() can race to remove the same entry, enabling a use-after-free in proc_re...

CVE-2026-74478

CVE-2026-74478 affects the Linux kernel, specifically the vector_mmsg_rx() path. When a packet is discarded because verify_header() fails, the code previously continued without advancing the slot, leaving a freed skb in the vector and causing a use-after-free in the RX path. The issue can be trig...

CVE-2026-74477

CVE-2026-74477 affects the Linux kernel uprobe handling, specifically a NULL pointer dereference in hprobe_expire() during forking a task with a pending uretprobe. The issue can occur in the clone path, with a NULL uprobe check leading to an OOPS in the hprobe_expire flow (uprobe_copy_process → c...

CVE-2026-74476

The CVE-2026-74476 entry describes a Linux kernel vulnerability in the veth path where a frag_list skb can reach veth with data_len set but nr_frags zero. The root cause is that veth_convert_skb_to_xdp_buff() could expose frag_list data to XDP as if it were in frags[], even though frags[] is empt...

CVE-2026-74474

CVE-2026-74474 pertains to the Linux kernel where the transmit path in VXLAN code (vxlan_xmit, arp_reduce, vxlan_mdb_entry_skb_get) used pskb_may_pull() to verify network-layer header availability. Because skb->data points to the MAC header (offset ~ ETH_HLEN), pskb_may_pull() could fail to ac...

CVE-2026-74475

CVE-2026-74475 affects the Linux kernel VXLAN path where the neighbour hardware address (n->ha) can be updated asynchronously. The patch fixes a potential torn/read-partially updated MAC address by using neigh_ha_snapshot() in route_shortcircuit() under the proper read_seqbegin()/read_seqretry...

CVE-2026-74473

CVE-2026-74473 affects the Linux kernel’s VXLAN path. The issue arises in route_shortcircuit() which originally used pskb_may_pull() to ensure a network header length, but skb->data points to the MAC header in vxlan_xmit(), making the check insufficient and risking reading beyond the pulled bu...

CVE-2026-74471

In the Linux kernel tracing subsystem, CVE-2026-74471 is caused by trace_module_add_events() ignoring the return value of __register_event(): if registration fails, a trace_event_call may still be linked via __add_event_to_tracers(), creating a stale pointer that can lead to a use-after-free when...

CVE-2026-74472

CVE-2026-74472 affects the Linux kernel ublk path. The vulnerability arises because ublk_ctrl_add_dev() memcpy()s userspace dev_info into ub->dev_info but does not reset two driver-owned fields: ->state and ->ublksrv_pid. This can cause a device added with state LIVE to pass a test for “...

CVE-2026-74470

The CVE-2026-74470 issue affects the Linux kernel in the scsi_debug path for REPORT ZONES replies. The vulnerability arises from an alloc_len handling bug where resp_report_zones() derives arr_len and rep_max_zones from the CDB alloc_len; for large alloc_len (0xFFFFFFC1..0xFFFFFFFF) ALIGN() can p...

CVE-2026-74469

The CVE-2026-74469 issue affects the Linux kernel SCTP implementation. It occurs in sctp_assoc_add_peer(), where a 16-bit transport_count is incremented for each new unique peer; once the 65,536th transport is added, the counter wraps to zero. SCTP sock_diag uses transport_count to reserve the IN...

CVE-2026-74468

The CVE-2026-74468 vulnerability affects the Linux kernel GPIO subsystem for the pch (Platform Controller Hub) driver. The root cause is that pch_irq_type() uses a spinlock (chip->spinlock) with spin_lock_irqsave() while __irq_set_trigger() is invoked with desc->lock held (a raw_spinlock_t)...

CVE-2026-74466

The CVE-2026-74466 vulnerability concerns the Linux kernel’s s390/zcrypt path. A domain value is extracted from a CCA or EP11 ioctl struct and, under certain conditions (custom device node, administrative load), is used as an array index after bounds checking without a speculation barrier. This c...
