CVE-2026-10647 Deadlock denial of service in USB CDC-NCM device class on TX enqueue failure

The USB CDC-NCM device class subsys/usb/devicenext/class/usbdcdcncm.c ignores the return value of usbdepenqueue in its ethernet transmit callback cdcncmsend. When the enqueue fails, the function still calls ksemtake&data-syncsem, KFOREVER, blocking on a completion semaphore that is only ever...

CVE-2026-53037

A flaw was found in the Linux kernel's USB Human Interface Device HID subsystem. This vulnerability occurs when a USB device, containing both HID and storage or Universal Attached SCSI UAS components, is reset. During the reset process, memory allocation operations within the hidpostreset functio...

CVE-2026-53194

A flaw was found in the Linux kernel's kl5kusb105 USB serial driver. This buffer overflow vulnerability allows a local attacker to write data beyond the intended memory boundary if attacker controls USB device or driver, because triggered from the internals of the device. By sending a specially...

SUSE CVE-2026-53037

In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix deadlock in hidpostreset You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hidprereset and hidpostreset are in the...

CVE-2026-53195

A flaw was found in the USB: serial: ioti module of the Linux kernel. The buildi2cfwhdr function allocates a fixed-size buffer but copies data into it without properly validating the input length from the firmware header. This oversight allows an attacker to provide a crafted firmware image,...

CVE-2026-53107

A flaw was found in the Linux kernel's Wi-Fi Libertas driver. This issue occurs when the system attempts to terminate USB Request Blocks URBs from an interrupt context, which can lead to the system attempting to sleep in an inappropriate context. This can cause system instability or prevent furth...

UBUNTU-CVE-2026-53196

In the Linux kernel, the following vulnerability has been resolved: USB: serial: ioti: fix heap overflow in getmanufinfo getmanufinfo reads le16tocpuromdesc-Size bytes from the device I2C EEPROM into a buffer allocated with kmallocobj, which is sizeofstruct edgetimanufdescriptor = 10 bytes. The...

CVE-2026-53196 USB: serial: io_ti: fix heap overflow in get_manuf_info()

In the Linux kernel, the following vulnerability has been resolved: USB: serial: ioti: fix heap overflow in getmanufinfo getmanufinfo reads le16tocpuromdesc-Size bytes from the device I2C EEPROM into a buffer allocated with kmallocobj, which is sizeofstruct edgetimanufdescriptor = 10 bytes. The...

CVE-2026-53195

The CVE-2026-53195 issue affects the Linux kernel USB: serial: io_ti driver. build_i2c_fw_hdr() allocates a fixed buffer and copies img_header->Length (up to 65535) without validating it against remaining space, enabling a potential heap overflow. The root cause is that check_fw_sanity() valid...

CVE-2026-53195

In the Linux kernel, the following vulnerability has been resolved: USB: serial: ioti: fix heap overflow in buildi2cfwhdr buildi2cfwhdr allocates a fixed-size buffer of 161024 - 512 + sizeofstruct tii2cfirmwarerec bytes, then copies le16tocpuimgheader-Length bytes into it without validating that...

CVE-2026-52964 ALSA: usb-audio: Bound MIDI 2.0 endpoint descriptor scans

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI 2.0 endpoint descriptor scans The USB MIDI 2.0 endpoint parser has the same descriptor walking pattern as the legacy MIDI parser. It validates bLength against bNumGrpTrmBlock before reading...

CVE-2026-52964

Summary of CVE-2026-52964 : A flaw in the Linux kernel’s ALSA USB-audio path (USB MIDI 2.0 endpoint parser) fails to validate descriptor lengths for the MIDI 2.0 endpoint, allowing a malformed device to cause out-of-bounds reads on baAssoGrpTrmBlkID[] due to walking endpoint extras before verifyi...
