An issue was discovered in the Linux kernel before 5.0.14. There is a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver.

An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver.

An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/usb/cpia2/cpia2_usb.c driver.

An issue was discovered in the Linux kernel before 5.1.17. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/line6/pcm.c driver.

A vulnerability was reported in various BIOS versions of older ThinkPad systems that could allow a user with administrative privileges or physical access the ability to update the Embedded Controller with unsigned firmware.

In the Linux kernel before 4.16.4, a double free vulnerability in the f_midi_set_alt function of drivers/usb/gadget/function/f_midi.c in the f_midi driver may allow attackers to cause a denial of service or possibly have unspecified other impact.

A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device.

An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c.

Buffer overflow in system firmware for EDK II may allow unauthenticated user to potentially enable escalation of privilege and/or denial of service via network access.

A vulnerability in the file system permissions of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to access sensitive information that is stored in the file system of an affected system. The vulnerability is due to improper implementation of file system permissions. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow the attacker to access sensitive and critical files. Firepower 4100 Series Next-Generation Firewalls are affected in versions prior to 2.2.2.91 and 2.3.1.110.
