Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-63923
High

In the Linux kernel, the octeontx2-af driver has a vulnerability allowing out-of-bounds memory write. The rvu_mbox_handler_rep_event_notify function does not validate the pcifunc field in the request, enabling an attacker to write past the allocated PF/VF structure array.

CVE-2026-63921
High

In the Linux kernel VTI (Virtual Tunnel Interface) driver for IPv6, a vulnerability allows an unprivileged user in a network namespace to hijack a VTI tunnel from another namespace. The issue stems from using dev_net(dev) instead of t->net in the tunnel lookup within vti6_siocdevprivate(), enabling hash table manipulation after tunnel migration.

CVE-2026-63920
High

In the Linux kernel, a vulnerability in IPv6 extension header handling allows an unprivileged user to trigger a slab-out-of-bounds read via nftables payload-write, as the header length is not re-validated before copying to cmsg.

CVE-2026-63919
HighEPSS 51%

A vulnerability was found in the Linux kernel's xfrm module related to transport-mode packet processing. During deferred transport reinjection, a pointer to the network namespace (netns) stored in skb->cb may become invalid if the namespace is removed before the callback executes.

CVE-2026-63918
High

In the Linux kernel's L2TP module, a vulnerability was found where l2tp_session_get_by_ifname() uses plain refcount_inc() instead of refcount_inc_not_zero(). This can cause a race condition returning a pointer to a session with a zero reference count, leading to a use-after-free.

CVE-2026-63917
High

A vulnerability in the Linux kernel's VTI6 (Virtual Tunnel Interface for IPv6) driver was found. After moving a VTI6 interface between network namespaces (netns), the vti6_changelink() and vti6_update() functions use a stale network reference (dev_net instead of t->net), leaving a stale entry in the original namespace's hash table. This causes a kernel BUG when cleaning up that namespace, allowing an attacker in an unprivileged container to crash the system.

CVE-2026-63916
High

A vulnerability was found in the Linux kernel's HID driver for Wacom tablets. The wacom_hid_set_device_mode() function assumes that the HID_DG_INPUTMODE usage is always in the first field of the report, which can lead to an out-of-bounds (OOB) write if the usage is located in a different field.

CVE-2026-63915
High

In the Linux kernel, an out-of-bounds read vulnerability exists in the NFC HCI stack within nfc_hci_recv_from_llc() and nci_hci_data_received_cb(). A malicious NFC peer can send a zero-length HCP frame, causing an out-of-bounds heap read and potentially a skb_over_panic during reassembly.

CVE-2026-63914
High

In the Linux kernel, a vulnerability was found in the XFRM (IPsec) migration mechanism. Functions sending migration notifications (xfrm_send_migrate and pfkey_send_migrate) incorrectly routed them to the default network namespace (init_net) instead of the caller's namespace. This caused IKE daemons in other namespaces to never receive their own migration notifications, while daemons in init_net received notifications from all namespaces.

CVE-2026-63913
HighEPSS 62%

A vulnerability in the Linux kernel's netfilter conntrack TCP module allows an RST packet with an invalid sequence number to force a connection into the CLOSE state without proper direction validation. This can prematurely terminate active NAT entries.

CVE-2026-63911
High

In the Linux kernel, the xfrm iptfs module has a vulnerability due to improper cloning of runtime state when copying Security Associations (SAs). The iptfs_clone_state() function copies runtime objects such as skb queues, timers, and spinlocks that should not be shared with the original SA, leading to use-after-free and double-free memory issues.

CVE-2026-63910
High

A use-after-free (UAF) vulnerability was found in the Linux kernel's dma_buf_fd() function related to a tracepoint. After FD_ADD() returns, the file descriptor becomes live in the descriptor table, allowing another thread to close it before DMA_BUF_TRACE() executes, causing a use-after-free of the dma_buf structure.

CVE-2026-63909
HighEPSS 50%

In the Linux kernel's ksmbd filesystem, a regression causes an out-of-bounds (OOB) read in the ACE-walk loop of smb_check_perm_dacl(). The flaw stems from a transposed bounds check that never breaks the loop, allowing a 2-byte heap OOB read past the allocated pntsd buffer during SMB2_CREATE operations.

CVE-2026-63907
High

In the Linux kernel UIO driver, a double free of devm_kzalloc() memory was found. The probe() and remove() functions explicitly call kfree() on a structure that is automatically freed by the devres mechanism, causing a double free.

CVE-2026-63906
High

A use-after-free vulnerability was found in the Linux kernel's USB MUSB driver for the OMAP2430 platform. The omap2430_probe() function calls of_node_put(np) before the last access to the node, potentially leading to use of freed memory.

CVE-2026-63905
High

A use-after-free vulnerability was found in the Linux kernel's USB/IP vudc driver. During device removal (vudc_remove), a race condition can cause the timer to still be active while the vudc structure is freed, leading to access to freed memory.

CVE-2026-63904
High

In the Linux kernel, a vulnerability in the USB USBTMC driver fails to check the actual_length of URB data for interrupt-IN notifications. This can lead to out-of-bounds reads or use of stale data.

CVE-2026-63903
High

In the Linux kernel's belkin_sa USB serial driver, the interrupt callback lacks validation of the received data length. Short interrupt packets can cause out-of-bounds reads (slab-out-of-bounds) when parsing LSR/MSR status fields.

CVE-2026-63902
High

In the Linux kernel's cypress_m8 USB serial driver, a vulnerability allows out-of-bounds read due to missing validation of interrupt packet headers. The cypress_read_int_callback() function did not check if the received packet contains the required header before reading it, which can lead to out-of-bounds memory access on short transfers.

CVE-2026-63901
High

A vulnerability in the Linux kernel's USB digi_acceleport driver can cause memory corruption due to missing bulk-out buffer size validation. A malicious USB device could report smaller buffers than expected, leading to out-of-bounds memory access or slab corruption.
