The vulnerability of the digi_port_init() function in the drivers/usb/serial/digi_acceleport.c file of the Linux operating system’s USB device driver module allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the digiportinit function in the drivers/usb/serial/digiacceleport.c module of the Linux device driver framework is related to the occurrence of operations outside the buffer in memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

CVE-2026-64335

A flaw was found in the Linux kernel's USB serial digiacceleport driver. This vulnerability occurs when a port is closed while it is in a throttled state, preventing the read Urban Request Block URB from being resubmitted. As a result, the affected port will cease to receive any further data,...
