CVE-2026-64459

Summary: CVE-2026-64459 is a use-after-free risk in the Linux kernel TCP-AO code. A previous patch removed the RCU-based freeing of TCP-AO/TCP-MD5 info in tcp_ao_destroy_sock(), which could allow a race during socket connect when a socket is in TCP_SYN_SENT and still discoverable in the hash/inbo...

CVE-2026-64457

The CVE-2026-64457 issue affects the Linux kernel’s virtio_pci subsystem. When unbinding a virtio balloon device (e.g., echo virtio0 > /sys/bus/virtio/drivers/virtio_balloon/unbind), a NULL pointer dereference can occur due to a mismatch between sparse queue indices and dense queue indices (ho...

CVE-2026-64456

CVE-2026-64456 affects the Linux kernel virtio-rng driver. A malicious or buggy virtio-rng backend can over-report used.len to trap memcpy past the inline data buffer, reading adjacent slab memory. This enables a potential cross-boundary data leak of guest-kernel heap contents via /dev/hwrng and ...

CVE-2026-64452 (Linux kernel 6LoWPAN) involves a race condition in 6LoWPAN’s Next Header Compression (NHC) handling that can cause a use-after-free in lowpan_nhc_do_uncompression when an NHC descriptor is freed while another path accesses nhc->name in an error path. The issue arises from holdi...

CVE-2026-64451

CVE-2026-64451 (Linux kernel) resolves a NULL pointer dereference in tracing: func_set_flag() dereferences tr->current_trace_flags before verifying the active tracer. If the function tracer is not active (e.g., switched to wakeup_rt), current_trace_flags can be NULL, causing a crash. Call path...

CVE-2026-64450

CVE-2026-64450: In Linux kernel TIPC, a broadcast Gap ACK blocks record could be read out-of-bounds due to a missing check that the record fits in the message data area. The bug occurs when tipc_get_gap_ack_blks() validates the len against ugack/bgack counts but not msg_data_sz(), allowing a reco...

CVE-2026-64449

CVE-2026-64449 relates to the Linux kernel staging/vme_user code. The vulnerability arises because the SLAVE-path helpers buffer_to_user() and buffer_from_user() copy count bytes using an unsafe offset (*ppos) into a fixed-size kern_buf (128 KiB), without bounding *ppos + count against size_buf. ...

CVE-2026-64447

CVE-2026-64447 maps to a Linux kernel issue in staging: ipu7 where pdata allocated in ipu7_isys_init() and ipu7_psys_init() can be freed twice via kfree pData in error paths. The two faulty paths are: (1) ipu7_mmu_init() fail leads to put_device() dropping refcount and freeing pdata via ipu7_bus_...

CVE-2026-64448

Summary (CVE-2026-64448): The Linux kernel fix addresses a SMB2 negotiation bug in CIFS/NTLM handling.

Summary of CVE-2026-64431 (Linux kernel NTFS driver): A memory corruption vulnerability arises when post_write_mst_fixup() is called for an invalid index_block after ntfs_ib_write() returns an error. The root cause is that ntfs_icx_ib_sync_write() treated any error as a write failure and invoked ...

CVE-2026-64430

CVE-2026-64430 affects the Linux kernel NTB EPF subsystem. ntb_epf_vec_isr previously called pci_irq_vector() in hardirq context, and pci_irq_vector() may call msi_get_virq() which takes a mutex and can trigger scheduling while atomic. The fix caches the Linux IRQ number for vector 0 when vectors...

CVE-2026-64429

CVE-2026-64429 : In the Linux kernel, the gpio eic-sprd driver used a sleeping lock during irq startup (spin_lock_irqsave) which could be invoked from an irq_startup path, leading to a sleeping function in an invalid context on PREEMPT_RT. The fix converts the Spreadtrum EIC controller lock to a ...

CVE-2026-64428

In CVE-2026-64428, a Linux kernel vulnerability was fixed in the GPIO SCH irq path. The issue arose because sch_irq_unmask() enables the GPIO IRQ and then updates controller state via sch_irq_mask_unmask(), which uses sch->lock with spin_lock_irqsave(). The callback could reach irq_startup() w...

CVE-2026-64427

Consolidated data for CVE-2026-64427 shows a resolved Linux kernel HID issue in the Logitech DJ driver. Root cause: the DJ short report validation could dereference rep->field[0] when rep->maxfield was zero, even after a prior fix, due to a crafted descriptor that creates a 0x20 report with...

CVE-2026-64426

Summary (CVE-2026-64426) Multiple sources describe a Linux kernel vulnerability in io_uring/nop where a file reference leak occurs when IOSQE_FIXED_FILE is set but IORING_NOP_FIXED_FILE is not; if REQ_F_FIXED_FILE is set, io_nop() may take the normal path and grab a real reference via io_file_get...

CVE-2026-64425

CVE-2026-64425 affects the Linux kernel io_uring/io-wq component.

CVE-2026-64423

CVE-2026-64423 affects the Linux kernel IPv4 IGMP multicast handling. The root cause is that, when a device is destroyed, ip_mc_destroy_dev() decrements the multicast membership refcount but fails to unlink the membership from the device’s multicast hash table (mc_hash) before RCUs reclaim the ob...

CVE-2026-64422

CVE-2026-64422 describes a Linux kernel vulnerability in net/ipv4: bound TCP reordering sysctl writes and MTU probe sizes. The issue arises when negative values written to net.ipv4.tcp_reordering are copied into the u32 tp->reordering field for new sockets, allowing wraparound and potential mi...

CVE-2026-64420

Summary : CVE-2026-64420 affects the Linux kernel in the Cros EC (ChromeOS) subsystem.

Th...

CVE-2026-64421

The CVE-2026-64421 issue affects the Linux kernel driver for imx8-isi (NXP), causing a slab-use-after-free in __media_entity_remove_link() during rmmod. The root cause is in mxc_isi_remove() calling mxc_isi_crossbar_cleanup() before mxc_isi_v4l2_cleanup(), which frees media entity pads that later...

CVE-2026-64419

The CVE-2026-64419 entry concerns the Linux kernel mm/shrinker path, where shrinker_debugfs_count_show() invokes the ->count_objects() callback while holding rcu_read_lock, allowing a sleep in that context. The root cause is that the debugfs count probe for memcg-aware shrinkers slept inside a...

CVE-2026-64418

CVE-2026-64418 is a Linux kernel memory-management race in the shrinker subsystem. The vulnerability arises when the shrinker_info array is freed while still accessible, causing use-after-free or double-free.

CVE-2026-64413

CVE-2026-64413 relates to the Linux kernel netfilter/ebtables path, specifically the zero chainstack array issue. The advisory describes that if cpu_possible_mask is sparse (e.g., CPU 0 and CPU 2 possible, CPU 1 not), the allocation loop can skip an entry and, if vmalloc_node() fails later, the c...

CVE-2026-64412

The CVE-2026-64412 issue affects the Linux kernel’s netfilter ebtables component, where module names must be null-terminated. The root cause is failing to explicitly check length, which could allow passing a non-null terminated string to request_module(), potentially enabling a local impact as de...

CVE-2026-64411

Linux kernel vulnerability CVE-2026-64411 affects netfilter/ebtables: update_counters() and compat_update_counters() pass a 32-byte user-supplied table name to find_table_lock() without NUL-termination, allowing vsnprintf() to read past the name and trigger a KASAN stack-out-of-bounds condition. ...

CVE-2026-64410

The CVE-2026-64410 entry concerns the Linux kernel netfilter flowtable for IPIP tunnels where hardware offload is not yet supported.
