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...

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

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...

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...

CVE-2026-52963

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI endpoint descriptor scans sndusbmidigetmsinfo validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID, but the descriptor walker can still return a class-specific...

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 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: typec: bus: verify partner exists in typecaltmodeattention Some USB hubs will negotiate DisplayPort Alt mode with the device. However, they will then negotiate a data role swap after entering the Alt mode. This data role swa...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: early: xhci-dbc: Fixed a potential out-of-bound memory access issue. If xdbcbulkwrite fails, the values in ‘buf’ can be anything. Therefore, it is not guaranteed that the string will be terminated with NULL when xdbcTrace is...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: USB: usbtmc: prevented kernel-usb-infoleak. The syzbot reported a kernel-usb-infoleak in usbtmcwrite; we need to clear the structure before filling the fields...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: char: xillybus: Check USB endpoints when probing the device. Ensure that, as the driver probes the device, all endpoints that the driver may attempt to access exist and are of the correct type. All XillyUSB devices must have a Bu...

Astra Linux – Vulnerability in Chromium

In Google Chrome versions prior to 88.0.4324.96, uninitialized usage in USB devices allowed a local attacker to potentially perform out-of-bound memory access through a USB device...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: can: gsusb: gsusbopen/close: fixed a memory leak. The gsusb driver appears to have a problem common to many USB CAN adapter drivers. It performs usballoccoherent to allocate a number of USB Request Blocks URBs for reception, and...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: USB: core: Fixed a hang issue in usbkillurb by adding memory barriers. The syzbot fuzzer has identified a bug in which processes hang while waiting for usbkillurb to return. It turns out that the issue isn’t related to unmounting...
