The vulnerability of the svdm_consume_modes() function in the drivers/usb/typec/tcpm/tcpm.c file of the driver for USB TypeC port controllers in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the svdmconsumemodes function in the drivers/usb/typec/tcpm/tcpm.c module of the USB TypeC port controller driver in the Linux operating system is related to the occurrence of operations outside the buffer in memory. Exploiting this vulnerability could allow a remote attacker...

CVE-2026-64330

A flaw was found in the Linux kernel's USB Type-C subsystem tcpm. A malicious USB-C partner device could exploit an out-of-bounds read vulnerability in the svdmconsumemodes function. By manipulating the SVID Standard or Vendor ID index, the partner device can force the system to register an...

CVE-2026-63962 usb: typec: tcpm: bound altmode_desc[] per iteration in svdm_consume_modes()

In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpm: bound altmodedesc per iteration in svdmconsumemodes svdmconsumemodes checks pmdata-altmodes against the array size once before the loop over the count, but forgot to check the bound at every point in the loop. I...
