CVE-2026-89743

A vulnerability in the Linux kernel's NSM (Network Shared Memory) driver allows a malicious or buggy backend to report a response length larger than the allocated buffer. The function nsm_sendrecv_msg_locked() stores the virtqueue used-ring length without bounding it, so parse_resp_raw() copies e...

CVE-2026-89742

CVE-2026-89742 is a use-after-free vulnerability in the Linux kernel's RapidIO mport character device driver , specifically in the dma_req_free() function. After kref_put() drops the last reference to a mapping and the mapping is freed by mport_release_mapping(), a subsequent mutex_unlock() deref...

CVE-2026-89740

CVE-2026-89740 is a dangling pointer vulnerability in the Linux kernel's imx UART (serial) driver . imx_uart_probe() publishes its devm-allocated port in the imx_uart_ports[] table before calling uart_add_one_port(), but the entry is not cleared on failure or after removal, leaving a stale pointe...

CVE-2026-89741

A double-free vulnerability exists in the Linux kernel's media subsystem , specifically in the v4l2-dev component's __video_register_device() function. A prior error-handling patch (commit 2a934fdb01db6458288fc9386d3d8ceba6dd551a) introduced the flaw: when device_register() fails, put_device() fr...

CVE-2026-89739

CVE-2026-89739 is a use-after-free in the Linux kernel 's USB DWC3 gadget driver. When a USB gadget is removed, dwc3_gadget_free_endpoints frees endpoint memory via kfree(dep), but a delayed work (dwc3_nostream_work) previously queued on system_percpu_wq during a DEPEVT_STREAM_NOSTREAM event may ...

CVE-2026-89738

CVE-2026-89738 is a use-after-free in the Linux kernel's at91_udc USB gadget driver. In polled-VBUS mode , a self-restarting timer/work cycle is not drained before the udc object is freed during a normal driver unbind or probe failure, allowing a pending or running timer callback to dereference f...

CVE-2026-89737

CVE-2026-89737 affects the Linux kernel USB Type-C Thunderbolt altmode driver. The root cause is a use-after-free in tbt_altmode_remove(), which drops the plug and cable references without first draining tbt->work. The work function can dereference those freed references and can also requeue i...

CVE-2026-89736

CVE-2026-89736 is a use-after-free (UAF) in the Linux kernel's USB audio gadget driver (u_audio). During sound card disconnection, g_audio_cleanup() frees the struct snd_uac_chip context immediately after snd_card_free_when_closed() returns, but ALSA control elements (kctls) may still be open in ...

CVE-2026-89735

CVE-2026-89735 is a memory leak in the Linux kernel 's USB gadget MIDI 2.0 driver. During function teardown in f_midi2_free_inst() or endpoint cleanup in f_midi2_ep_opts_release(), the function configfs_remove_default_groups() was never called, so the internal refcounts of the default configfs ch...

CVE-2026-89734

CVE-2026-89734 is a null pointer dereference in the Linux kernel's USB gadget UVC driver. In the function uvcg_video_init(), if kthread_run_worker() fails, the error-handling path invokes uvcg_err(), which dereferences video->uvc. However, at that point in initialization the pointer has not ye...

CVE-2026-89733

A use-after-free (UAF) vulnerability exists in the Linux kernel USB gadget UVC driver . In the error path of uvc_function_bind() and in uvc_function_unbind(), the pointers uvc->control_req and uvc->control_buf are freed but not set to NULL , leaving dangling pointers that can be dereference...

CVE-2026-89731

CVE-2026-89731 is an out-of-bounds read in the Linux kernel CXL/RAS subsystem, specifically in the cxl_rch_get_aer_info() function. The function copies the RCH Downstream Port AER capability from the RCRB MMIO block using a readl() loop bounded by sizeof(struct aer_capability_regs). Since struct ...

CVE-2026-89732

CVE-2026-89732 is a deadlock in the Linux kernel 's USB gadget f_fs (function filesystem) subsystem. The root cause is that ffs_ep0_read() holds ffs->mutex while calling wait_event_interruptible_exclusive_locked_irq(), which sleeps without releasing the mutex. When a userspace daemon is pollin...

CVE-2026-89730

CVE-2026-89730 affects the Linux kernel 's altera-cvp FPGA driver. In the function altera_cvp_send_block() , the trailing-byte code path dereferences a u32 pointer even when only 1–3 bytes remain in the input buffer. When the buffer ends at a page or scatterlist boundary, this causes an out-of-bo...

CVE-2026-89729

CVE-2026-89729 is an out-of-bounds write in the Linux kernel's HID sensor-hub driver. The sensor_hub_get_feature() function clamps its return value to the caller's buffer size, but the internal copy loop still writes field->report_size / 8 bytes per value. A malicious HID descriptor advertisin...

CVE-2026-89728

This vulnerability affects the Linux kernel 's Renesas I3C driver (i3c:renesas). During Dynamic Address Assignment (DAA) , the controller reports results via the NRSPQP register. When the I3C bus is empty , the data length field in the response descriptor returns the controller's maximum device c...

CVE-2026-89727

CVE-2026-89727 affects the Linux kernel KVM arm64 GICv2 implementation. In vgic_v2_deactivate(), a guest-written INTID is passed directly to vgic_get_vcpu_irq(), where a failed lookup triggers WARN_ON_ONCE()—treated as a "can't happen" condition. Since GICv2 has no LPIs, any INTID outside the SGI...

CVE-2026-89726

CVE-2026-89726 is an off-by-one out-of-bounds read in the Linux kernel's lib/ucs2_string.c, specifically in the ucs2_strnlen() function. The root cause is that ucs2_strnlen() checks the current character before verifying whether the caller-provided maximum length has been reached. If the input is...

CVE-2026-89725

CVE-2026-89725 affects the Linux kernel's media: cec: stm32 driver, where stm32_rx_done() writes received CEC bytes into a fixed 16-byte buffer (rx_msg.msg[]) without bounds-checking the write index. A remote CEC device on an adjacent network that transmits bytes without an end-of-message signal ...

CVE-2026-89723

CVE-2026-89723 affects the nilfs2 file system component of the Linux kernel . The root cause is that when a B-tree mapping collapses into a direct mapping during file truncation, an intermediate node block immediately below the B-tree root is left orphaned in the B-tree node cache in a dirty stat...
