CVE-2026-45923

A flaw was found in the Linux kernel's net: usb: catc driver. A malformed Universal Serial Bus USB device can present endpoint descriptors with transfer types that differ from what the driver expects. This can lead to the driver attempting to use incorrect endpoint types, potentially causing...

CVE-2026-45923

Summary: CVE-2026-45923 affects the Linux kernel’s USB-CATC driver. Affected codePath: probe time endpoint verification for CATC USB endpoints. Root cause: CATC probe uses hardcoded endpoint pipes (TX/RX bulk 1, interrupt status 2) without validating endpoint descriptors, allowing a malformed USB...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from the assumption that reserved bits are always 0 when parsing endpoint descriptors, which could lead to incorrectl...

SUSE CVE-2016-20022

In the Linux kernel before 4.8, usbparseendpoint in drivers/usb/core/config.c does not validate the wMaxPacketSize field of an endpoint descriptor. NOTE: This vulnerability only affects products that are no longer supported by the supplier...

SUSE CVE-2016-3138

The acmprobe function in drivers/usb/class/cdc-acm.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service NULL pointer dereference and system crash via a USB device without both a control and a data endpoint descriptor...

UBUNTU-CVE-2021-42553

A buffer overflow vulnerability in stm32mwusbhost of STMicroelectronics in versions before 3.5.1 allows an attacker to execute arbitrary code when the descriptor contains more endpoints than USBHMAXNUMENDPOINTS. The library is typically integrated when using a RTOS such as FreeRTOS on STM32 MCUs...

kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash

A null pointer dereference flaw was discovered in the Linux kernel's implementation of the ath10k USB device driver. The vulnerability requires the attacker to plug in a specially crafted hardware device that present endpoint descriptors that normal ath10k devices do not recognize. System...
