CVE-2026-89621

A flaw was found in the Linux kernel's HID Human Interface Device mcp2221 driver. A malicious USB device can exploit this vulnerability by sending a specially crafted, short HID report with an invalid size. This can cause the system to read past valid memory, leading to the disclosure of sensitiv...

CVE-2026-89471

A flaw was found in the Linux kernel's crosusbpd-charger driver. A malicious or compromised embedded controller EC can report an excessive number of USB Power Delivery PD ports. This causes the driver to write beyond the allocated memory buffer when populating a fixed-size array for port data,...

CVE-2026-89735

A flaw was found in the Linux kernel's USB gadget MIDI2 driver. The driver fails to properly remove default configuration file system configfs groups during teardown, leading to a resource leak. A local attacker could exploit this vulnerability to cause memory exhaustion, potentially resulting in...

CVE-2026-89736

A flaw was found in the Linux kernel's USB audio gadget driver uaudio. This vulnerability occurs during sound card disconnection when Asynchronous Linux Sound Architecture ALSA control elements kctls remain open in userspace. A local attacker can exploit this timing issue by interacting with thes...

CVE-2026-89732

A flaw was found in the Linux kernel's USB FunctionFS ffs module. A local attacker could exploit a deadlock vulnerability in the ffsep0read function. This occurs when a userspace daemon polls ep0 and the USB gadget is simultaneously torn down, causing the kernel to enter an unresponsive state. Th...

CVE-2026-80971

A flaw was found in the ALSA bcd2000 driver of the Linux kernel. When a USB device using this driver is disconnected while a rawmidi substream is still active, the driver fails to clear the Universal Serial Bus Request Block URB pointers. This oversight allows a local attacker to trigger a...

CVE-2026-80973

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture subsystem, specifically within the 6fire driver. This vulnerability allows a malicious USB device to trigger an out-of-bounds read by sending a specially crafted MIDI event with an excessive length. This can lead to the...
