QEMU: usb: out-of-bounds r/w access issue while processing usb packets
An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU. This issue occurs while processing USB packets from a guest when USBDevice 'setuplen' exceeds its 'databuf4096' in the dotokenin, dotokenout routines. This flaw allows a guest user to crash the QEMU process,...

kernel: race condition caused by a malicious USB device in the USB character device driver layer
A flaw was found in the Linux kernel, where there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer. An attacker who can hotplug at least two devices of this class can cause a use-after-free situation...
kernel: information leak bug caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver
An information-leak flaw was found in the Linux kernel's pcan USB driver. When a device using this driver connects to the system, the stack information is leaked to the CAN bus, a controller area network for automobiles. The highest threat with this vulnerability is breach of data confidentiality...
kernel: out of bounds write in i2c driver leads to local escalation of privilege
An out-of-bounds write flaw was found in the i2c driver in the Linux kernel. This flaw allows an attacker to escalate privileges with system execution privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...
kernel: out of bounds write in function i2c_smbus_xfer_emulated in drivers/i2c/i2c-core-smbus.c
An out of bounds OOB memory access flaw was found in i2csmbusxferemulated in drivers/i2c/i2c-core-smbus.c in I2C subsystem. A read request for length data-block0 greater than 'I2CSMBUSBLOCKMAX + 1' may cause underlying I2C driver write out of array's boundary. This could allow a local attacker wi...
Moderate: Red Hat Security Advisory: dbus security update
An update for dbus is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the C...
dbus: DBusServer DBUS_COOKIE_SHA1 authentication bypass
A flaw was found in dbus. The implementation of DBUSCOOKIESHA1 is susceptible to a symbolic link attack. A malicious client with write access to its own home directory could manipulate a /.dbus-keyrings symlink to cause the DBusServer to read and write in unintended locations resulting in an...
ibus: missing authorization allows local attacker to access the input bus of another user
A flaw was discovered in ibus that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface...

kernel: use-after-free caused by a malicious USB device in the drivers/usb/misc/adutux.c driver
A flaw was found in the Linux kernel’s implementation for ADU devices from Ontrak Control Systems, where an attacker with administrative privileges and access to a local account could pre-groom the memory and physically disconnect or unload a module. The attacker must be able to access either of...
kernel: null pointer dereference in drivers/media/usb/zr364xx/zr364xx.c driver
A vulnerability was found in the Linux kernel. The Zr364xx USB device driver is susceptible to malicious USB devices. An attacker able to add a specific USB device could cause a crash leading to a denial of service...
kernel: out of bounds write in function i2c_smbus_xfer_emulated in drivers/i2c/i2c-core-smbus.c
An out of bounds OOB memory access flaw was found in i2csmbusxferemulated in drivers/i2c/i2c-core-smbus.c in I2C subsystem.

kernel: a malicious USB device in the drivers/input/ff-memless.c leads to use-after-free
A use-after-free flaw was found in the Linux kernel’s input device driver functionality when unplugging a device. A user with physical access could use this flaw to crash the system...
kernel: use-after-free caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver
A use-after-free flaw was found in the acmprobe USB subsystem in the Linux kernel. A race condition occurs when a destroy procedure is initiated allowing the refcount to decrement on the interface so early that it is never under counted. A malicious USB device is required for exploit. System...
CVE-2020-25742
A NULL pointer dereference flaw was found in the LSI53C895A SCSI Host Bus Adapter emulator of QEMU. This flaw occurs while processing 'Memory Move' instructions to move data between DMA memory and I/O address space via lsimemcpy. This flaw allows a guest user or process to crash the QEMU process,...
