CVE-2006-2936

High
Published: Translated: NVD NIST

Summary

The ftdi_sio driver in Linux kernel 2.6.x up to 2.6.17 allows local users to cause a denial of service by writing more data to the serial port than the hardware can handle, leading to memory exhaustion due to queued data.

Risk Assessment

A local attacker can exhaust system memory, causing slowdowns or crashes, thereby impacting service availability.

Recommendation

Upgrade the Linux kernel to version 2.6.17.1 or later, which includes a fix to limit data queuing in the ftdi_sio driver.

The ftdi_sio driver (usb/serial/ftdi_sio.c) in Linux kernel 2.6.x up to 2.6.17, and possibly later versions, allows local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued.
