CVE-2026-74539

The CVE-2026-74539 entry affects the Linux kernel Bluetooth ISO path. The root cause is that accessing iso_pi(sk)->conn requires lock_sock, but the lock was not held in iso_sock_getname. The fix implemented is to add the appropriate lock and release around this usage. Documents from NVD/SUSE/O...

CVE-2026-74537

The CVE-2026-74537 entry concerns the Linux kernel Bluetooth ISO path. A use-after-free could occur when dereferencing conn->sk in iso_conn_ready because the socket was accessed without holding a lock or a refcount. The fix adds a socket refcount in iso_conn_ready and rechecks socket validity ...

CVE-2026-74536

In CVE-2026-74536, the Linux kernel Bluetooth ISO stack suffers a leak: iso_sock_kill() can leak the sk reference after socket release or when __iso_sock_close() does not set SOCK_ZAPPED, because sock_orphan(sk) marks SOCK_DEAD. The fix replaces SOCK_DEAD with a dedicated BT_SK_KILLED flag and ad...

CVE-2026-74535

CVE-2026-74535 affects the Linux kernel Bluetooth ISO subsystem. The vulnerability arises in iso_sock_timeout, which takes lock_sock; keeping the timer disabled while holding that lock may deadlock, and it can run concurrently with iso_conn_del(), leading to a use-after-free of hcon.iso_data. The...

CVE-2026-74533

CVE-2026-74533 is a Linux kernel vulnerability affecting Bluetooth ISO handling. Multiple sources (Linux kernel description, SUSE, NVD, Debian, EUVD, PT Security, etc.) describe a race where hci_conn::iso_data is accessed and modified without proper locking or RCU, enabling a stale reference use ...

CVE-2026-74534

CVE-2026-74534 : Linux kernel Bluetooth ISO subsystem contains a race in refcounting of iso_conn between iso_conn_del() and iso_chan_del(), causing a double-put of iso_conn when a connection is not associated with an sock. The fix, as described in the connected documents, is to let iso_pi(sk)-&gt...

CVE-2026-74532

In the Linux kernel Bluetooth subsystem, CVE-2026-74532 affects btintel: btintel_diagnostics() which reads tlv->val[0] without verifying the diagnostics TLV length, risking reads beyond the frame. The documented fix is to validate the TLV length before access. Connected sources (SUSE, NVD, Deb...

CVE-2026-74530

CVE-2026-74530 : Linux kernel Bluetooth vulnerability in the hci_sync path (hci_connect_big_sync) may allow a use-after-free if the conn is freed while the hci_sync task runs. The root cause is a potential UAF due to a conn lifecycle race; the fix holds a refcount to prevent use-after-free and ha...

CVE-2026-74531

CVE-2026-74531 affects the Linux kernel Bluetooth implementation, specifically the hci_conn path used by abort_conn_sync. The root cause is a potential use-after-free if the connection object is freed while the hci_sync task is running. The documented fix is to hold a reference (refcount) to the ...

CVE-2026-74528

The CVE refers to the Linux kernel Bluetooth subsystem: hci_sync in the hci_past_sync() callback, which previously could dereference freed pointers to hci_conn_valid() due to kmalloc reuse. The fix holds a reference count on the connection to ensure resources remain valid, preventing use-after-fr...

CVE-2026-74529

In the Linux kernel Bluetooth subsystem, the issue is in the hci_sync path: the conn object could be freed while the hci_sync task is running in hci_connect_pa_sync(), creating a theoretical use-after-free. The documented fix is to hold a refcount on the conn to prevent deallocation during the ca...

CVE-2026-74527

CVE-2026-74527 affects the Linux kernel’s octeontx2-af pathway. PF and VF NIX LFs sharing a CGX LMAC can reuse the same hardware PKIND programming; when HiGig2 or EDSA parsing is enabled, a VF NIX LF alloc must not reset the PF’s LMAC RX PKIND or default TX parse config. The fix adds cgx_get_pkin...

CVE-2026-74526

In CVE-2026-74526, the Linux kernel fault-handling code for mpi3mr (scsi) had a potential deadlock when GFP_KERNEL allocations in mpi3mr_fault_uevent_emit could trigger memory reclaim while host I/O was blocked. The fix covers the entire call with memalloc_noio_save()/restore(), replacing the pre...

CVE-2026-74525

CVE-2026-74525 affects the Linux kernel net sxgbe driver. When RX descriptor ring allocation fails, init_dma_desc_rings() frees partial RX rings but leaks TX rings allocated earlier. The fix rearranges error labels to clean up TX rings on RX failure. Affected component: net/sxgbe RX/TX ring initi...

CVE-2026-74524

CVE-2026-74524 : In the Linux kernel (RISC‑V), a fix prevents an out‑of‑bounds page‑table walk during memory hot‑remove. When page‑table levels are folded (Sv48 Sv39), remove_pud_mapping/remove_p4d_mapping compute child bases with pud_offset(p4dp,0) / p4d_offset(pgd,0) and then add an index that ...

CVE-2026-74523

Summary: CVE-2026-74523 affects the Linux kernel qede driver with VXLAN/GENEVE tunnels. A TX timeout can cause recovery deadlocks in the driver’s mutex, freezing rtnetlink control for the node. What’s affected: The qede UDP tunnel synchronization flow during recovery paths, where recovery nested ...

CVE-2026-74521

The CVE-2026-74521 vulnerability affects the Linux kernel’s ksmbd component, where ClientGUIDs were compared with strncmp() and could misclassify distinct GUIDs that contain embedded NUL bytes. The fix uses memcmp() to compare all SMB2_CLIENT_GUID_SIZE bytes in SMB3 multichannel session binding a...

CVE-2026-74522

The CVE-2026-74522 entry describes a Linux kernel ksmbd use-after-free in __close_file_table_ids(). A ksmbd_file can stay alive after logical close while another session holds a temporary reference, leading to a potential use-after-free when the final ksmbd_fd_put() path frees the object without ...

CVE-2026-74520

The CVE-2026-74520 issue is in the Linux kernel’s iommu/iommufd path, where iopf_group_alloc() links the last-page IOPF group into the generic pending list and iommufd_fault_iopf_handler() queues an accepted group in the IOMMUFD deliver list without removing it from the generic list. When a devic...

CVE-2026-74519

CVE-2026-74519 describes a Linux kernel vulnerability in the pinctrl devicetree handling: dt_remember_or_free_map() may free uninitialized dev_name entries if kstrdup_const() fails, leading to a KASAN double-free during cleanup in dt_free_map. The issue arises when pinctrl drivers (e.g., pinctrl-...
