Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the MCTP driver failing to release the USB device reference when detection fails, resulting in a...

CVE-2026-43251

A flaw was found in the Linux kernel's Human Interface Device HID prodikeys driver. A local attacker can exploit this vulnerability by connecting a specially crafted Universal Serial Bus USB device. This device can send a malicious report descriptor, bypassing a necessary check and causing a null...

CVE-2026-43140

A flaw was found in the Linux kernel's HID Human Interface Device magicmouse driver. A local attacker with physical access could exploit this vulnerability by connecting a specially crafted USB device. This device could send a malformed report descriptor, causing the msc-input to remain...

CVE-2026-43250

In the Linux kernel, the following vulnerability has been resolved: usb: chipidea: udc: fix DMA and SG cleanup in epnuke The ChipIdea UDC driver can encounter "not page aligned sg buffer" errors when a USB device is reconnected after being disconnected during an active transfer. This occurs becau...

CVE-2026-43140

In the Linux kernel, the following vulnerability has been resolved: HID: magicmouse: Do not crash on missing msc-input Fake USB devices can send their own report descriptors for which the inputmapping hook does not get called. In this case, msc-input stays NULL, leading to a crash at a later time...

CVE-2026-31778

A flaw was found in the Linux kernel's ALSA caiaq driver. A local user with a specially crafted USB device, containing a product name with many non-ASCII or non-space characters, can trigger a stack out-of-bounds read. This vulnerability allows the system to read past the end of a stack buffer,...

CVE-2026-31701

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: take a reference on the USB device in createcard The caiaq driver stores a pointer to the parent USB device in cdev-chip.dev but never takes a reference on it. The card's privatefree callback, sndusbcaiaqcardfree, ca...

CVE-2026-31701

In CVE-2026-31701, the Linux kernel ALSA caiaq driver (USB audio) stored a pointer to the parent usb_device without a reference. The snd_usb_caiaq_card_free() path can run after the USB device is disconnected, dereferencing freed memory (use-after-free). The fix is to take a reference on the USB ...

CVE-2026-31623

A flaw was found in the Linux kernel's cdc-phonet driver. A malicious USB device, pretending to be a CDC Phonet modem, can exploit this vulnerability by sending an unlimited number of large data transfers. This can cause an overflow in the kernel's internal data buffer skbsharedinfo-frags array,...

CVE-2026-31581

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

DEBIAN-CVE-2026-31623

In the Linux kernel, the following vulnerability has been resolved: net: usb: cdc-phonet: fix skb frags overflow in rxcomplete A malicious USB device claiming to be a CDC Phonet modem can overflow the skbsharedinfo-frags array by sending an unbounded sequence of full-page bulk transfers. Drop the...

CVE-2026-31650 mmc: vub300: fix use-after-free on disconnect

In the Linux kernel, the following vulnerability has been resolved: mmc: vub300: fix use-after-free on disconnect The vub300 driver maintains an explicit reference count for the controller and its driver data and the last reference can in theory be dropped after the driver has been unbound. This...

CVE-2026-31604

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: fix device leak on probe failure Driver core holds a reference to the USB interface and its parent USB device while the interface is bound to a driver and there is no need to take additional references unless the...

CVE-2026-31578

In the Linux kernel, the following vulnerability has been resolved: media: as102: fix to not free memory after the device is registered in as102usbprobe In as102usb driver, the following race condition occurs: CPU0 CPU1 as102usbprobe kzalloc; // alloc as102devt .... usbregisterdev; fd =...

PT-2026-34901

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The cp2615 driver uses the USB device serial string as the i2c adapter name without verifying that the string exists. This can lead to a NULL-pointer dereference, which occurs when the...

CVE-2025-13763

Multiple uses of uninitialized variables were found in libopensc that may lead to information disclosure or application crash. An attack requires a crafted USB device or smart card that would present the system with specially crafted responses to the APDUs...

CVE-2025-13763 Libopensc: opensc: multiple uses of uninitialized variable

Multiple uses of uninitialized variables were found in libopensc that may lead to information disclosure or application crash. An attack requires a crafted USB device or smart card that would present the system with specially crafted responses to the APDUs...

OpenSC 安全漏洞

OpenSC is an open-source smart card tool and middleware developed by OpenSC. There is a security vulnerability in OpenSC, which stems from the use of uninitialized variables multiple times, potentially leading to information leaks or application crashes.
