CVE-2026-90034

CVE-2026-90034 affects the Linux kernel's usb_mdc800 driver (USB Image MDC800). The root cause is the use of kmalloc() instead of kzalloc() for the irq_urb_buffer and download_urb_buffer allocations in usb_mdc800_init(). Because the memory is not zero-initialized, a shorter-than-expected message ...

CVE-2026-90033

CVE-2026-90033 is an out-of-bounds write in the Linux kernel 's ALSA usb-audio subsystem, specifically in the snd_usbmidi_us122l_output() function. The root cause is that the function uses a fixed transfer count of 2 on speeds below high-speed without checking ep->max_transfer. When a device (...

CVE-2026-90032

This is a use-after-free vulnerability in the Linux kernel's usbtv (USB TV) media driver. The ALSA PCM callbacks store driver state in pcm->private_data, and because usbtv_audio_free() uses snd_card_free_when_closed(), an open PCM file can outlive a USB disconnect. The disconnect path can then...

CVE-2026-90031

CVE-2026-90031 affects the Linux kernel's ene_ub6250 USB storage driver. The root cause is a race condition on the shared us->current_urb field: the delayed scan work (via usb_stor_Bulk_max_lun()) and the probe path (via ene_get_card_type()) both access it concurrently, with only the scan path...

CVE-2026-90029

CVE-2026-90029 is a use-after-free vulnerability in the Linux kernel 's USB storage realtek_cr driver, triggered on device disconnect . The root cause is that realtek_cr_destructor() calls timer_delete() before the chip containing the timer is freed, allowing the timer callback to rearm itself ag...

CVE-2026-90030

CVE-2026-90030 affects the Linux kernel USB DWC3 driver on DWC_usb31 v2.00a and v2.10a controllers. The root cause is the forceRM bit of the DEPCMD register being set to 1 when issuing the EndTransfer command, as recommended by older DWC3 programming guide revisions. With forceRM=1, a transfer ab...

CVE-2026-90028

CVE-2026-90028 affects the Linux kernel USB Type-C driver for the hd3ss3220 controller. The root cause is that regulator_is_enabled() reports the aggregate regulator state rather than whether this particular consumer holds an enable reference. When another consumer enables VBUS first, the driver ...

CVE-2026-90027

CVE-2026-90027 affects the Linux kernel's qcom-pmic-typec USB Type-C driver. A use-after-free race occurs when port_stop() returns before tcpm_unregister_port() destroys the TCPM kthread worker; flushing that worker during unregister can run a callback (set_cc() or start_toggling()) that re-queue...

CVE-2026-90026

CVE-2026-90026 is a use-after-free vulnerability in the Linux kernel 's USB Type-C Qualcomm PMIC driver. The root cause is a race condition: pdphy_stop() disables IRQs but leaves reset_work pending, so if the IRQ handler schedules the work just before disable_irq(), it can execute after remove() ...

CVE-2026-90025

CVE-2026-90025 is an out-of-bounds array index flaw in the Linux kernel's UCSI DisplayPort driver (usb: typec: ucsi: displayport). The driver uses the GET_CURRENT_CAM response value to index a port altmode array of fixed length UCSI_MAX_ALTMODES , but only validates that the value is not 0xff wit...

CVE-2026-90024

CVE-2026-90024 affects the Linux kernel USB gadget MIDI 2.0 function (drivers/usb/gadget/function/f_midi2.c). When the block direction is set to SNDRV_UMP_DIR_INPUT via configfs, the midi1_ep_out endpoint initialization is skipped during the gadget bind phase, leaving usb_ep->card as NULL . La...

CVE-2026-90023

CVE-2026-90023 is a null pointer dereference in the Linux kernel USB gadget f_mass_storage driver, specifically in fsg_common_set_num_buffers(). The root cause is that the earlier removal of fsg_num_buffers_validate() relied on Kconfig limits (2–256) for the buffer count n, but a user can write p...

CVE-2026-90022

CVE-2026-90022 is a use-after-free vulnerability in the Linux kernel 's USB gadget f_midi2 driver. The function f_midi2_opts_str_show() acquires the string lock internally, but its callers dereference the opts->info. pointer before calling it, outside the lock. This races with f_midi2_opts_str...

CVE-2026-90021

In the Linux kernel , the USB gadget f_midi driver contained a bug where INIT_WORK was performed in f_midi_bind() rather than f_midi_alloc(). If f_midi_bind() was never executed, the work struct remained uninitialized, causing f_midi_free to trigger a warning in __flush_work due to work->func ...

CVE-2026-90019

CVE-2026-90019 affects the Linux kernel USB gadget subsystem. In the UVC function implementation, usb_put_function_instance() dereferences fi->fd to retrieve the module reference in the uvc_alloc_inst() error path. However, fd is not allocated until later in try_get_usb_function_instance(), so...

CVE-2026-90020

CVE-2026-90020 affects the Linux kernel USB gadget subsystem. The vulnerability is a race condition in gadget_dev_ioctl(): the function reads dev->gadget before acquiring dev->lock, but checks dev->state only after acquiring the lock. A concurrent bind can change the device state between...

CVE-2026-90018

CVE-2026-90018 affects the rtl8723bs staging driver in the Linux kernel . The root cause is a missing bounds check on variable-length WPS attribute data in rtw_get_wps_attr(): the 4-byte header is validated against the Information Element length, but the attacker-controlled attr_data_len (up to 6...

CVE-2026-90017

CVE-2026-90017 is an out-of-bounds read in the Linux kernel's staging driver rtl8723bs , specifically in rtw_action_frame_parse(). The function accepts a frame_len parameter but never validates it before indexing into the frame body. Since frame_body already points 24 bytes into the frame, derefe...

CVE-2026-90016

CVE-2026-90016 is a 1-byte out-of-bounds read in the Linux kernel's staging rtl8723bs wireless driver, specifically in rtw_restruct_wmm_ie(). The function scans an attacker-influenced IE buffer (built from association/scan data) for a WMM IE. When the index reaches in_len - 1 without matching, ex...

CVE-2026-90015

CVE-2026-90015 affects the Linux kernel xHCI driver . When a Transfer Descriptor (TD) spans three or more ring segments, the driver's td->bounce_seg field records only the last bounced segment, leaving earlier bounce buffers neither copied back into the URB buffer nor DMA unmapped. The URB sti...
