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. By sending a specially crafted input to the USB serial port, an attacker can trigger an out-of-bounds write, which may...

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...

EUVD-2026-39286

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-2026-53195

In the Linux kernel USB serial driver io_ti, CVE-2026-53195 describes a heap-overflow in build_i2c_fw_hdr(). The function allocates a fixed buffer ((16*1024 - 512) + sizeof(struct ti_i2c_firmware_rec)) and then copies img_header->Length bytes without validating that Length fits into the remain...

EUVD-2026-38905

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...

kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: usb: dwc2: Fixed a device leak in hwenable upon suspend/resume. Every time the platform enters low-power mode, the PM suspend/resume routines call dwc2lowlevelhwenable - devmaddactionorreset. This adds a new device entry each...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y: Use sndcardfreewhenclosed when there is a disconnection. The USB disconnection callback should be short and not too long. Alternatively, the current code uses sndcardfree when there is a disconnection, but this waits...

Astra Linux – Vulnerability in Qemu

A reachable assertion issue was detected in the USB EHCI emulation code of QEMU. This issue can occur during the processing of USB requests due to a faulty handling of the DMA memory map. A malicious privileged user within the guest environment may exploit this flaw to send invalid USB requests,...

Astra Linux – Vulnerability in Linux 6.1
